Okinawan Pig's Feet Soup (Ashitibichi)

In ashitibichi, whole or sliced pig's feet, or trotters, are simmered with ginger to produce an incredibly savory and gelationous broth. Large cut vegetables are added to create a final dish that is more a stew than soup from a Western point of view. Either way, you will either love it or you won't even try it, depending on where you stand on the "odd meat-parts" divide of carnivorous dining. If you happen to fall on the other side of the divide, that's okay — more for the rest of us! *smile*
This is a dish that my mother did not make at home when we were growing up. I'm not sure why, because she enjoyed eating it whenever she came across it, I just don't remember seeing her make it. Ashitibichi is considerably more time-consuming to make than oden-style Kombu, so that may be one reason. For this recipe I had to consult my trusty, well-worn copy of "Okinawan Cookery and Culture" produced by the Okinawan women's group of Hawaii called Hui O Laulima. (Here is another version prepared by Pomai at Tasty Island — he may not be Okinawan, but he's a fan, too!)
As with many Okinawan specialties, ashitibichi features kombu, or kelp, as well as pork. The type of kombu needed for this dish is the long dried strips which may be labelled "nishime kombu," "hayani kombu" or "ma kombu" — any one of these will work with this preparation. Preparing the kombu before it is added to the soup takes a bit of prep work and is not intuitive to anyone not accustomed to using kombu, so here's a quick guideline.
PREPARING KOMBU KNOTS

First, soak the dried kombu in cold water, using a container large enough that you don't have to bend the dried strips — bending the strips can cause them to snap and cut your kombu before you can knot it. Soak for 30-40 minutes, or until the strips become pliable. Don't soak too long (2 or more hours) or the kombu will start to become mushy and unworkable.
Reserve 2 cups of the soaking water. (You can use excess kombu water as the foundation for a vegetarian stock or to cook dried beans — the kombu water is said to make the beans easier to digest, I haven't tried this yet but will. I also water planted vegetables and shrubs with this mineral-rich water, if I don't have an immediate use for it in the kitchen.)

Knot each strip of kombu 4-5 times, depending on the length of the vegetable. If you leave about 5 inches, or one fist-length (see photo above), between the knots, you will leave just enough room to cut between them and leave an adequate "tail" on either side of the knot. The kombu will continue to expand as it cooks and if you cut too close to the knot, it will unravel as the vegetable cooks and become an unattractive blob of seaweed. Beware the Blob — leave a tail on both sides of the knot!

ASHITIBICHI, OKINAWAN PIG'S FEET SOUP
(Mrs. Yukihide Kohatsu's and Mrs. Fumiko Miyasato's recipes in "Okinawan Cookery and Culture" were the starting points for this version, although the method is my own. Photo here is from the 2007 Okinawan Heritage Festival in Kapiolani Park, Oahu)
Begin at least one day before you plan to serve, since broth is cooled overnight.
For the Broth
3.5-4 lbs/1.6-1.8kg pig's feet, whole or sliced lengthwise
2 large fingers of ginger, scrubbed well and sliced lengthwise (leave skin on)
Enough water to cover meat by 1-2 inches

Place meat and ginger in large (6 qt/L, or larger) crockpot. Set on HIGH setting for 2 hours. Skim top of broth to remove impurities as they rise to surface.
After 2 hours, set to LOW and allow to simmer for 5 hours for sliced feet, 6-7 hours for whole trotters. Meat should be tender and move around the joints easily.
Remove meat to separate container for cooling and storage. Discard ginger, and strain broth. Cool completely and store overnight separately from meat.
To Finish Soup:
2-3 strips of dried kombu strips, soaked and knotted (see Preparing Kombu, above)
2 cups reserved kombu soaking water above
2-3 TBL awamori or sake
1 medium daikon, peeled and cut crosswise into 2-inch thick slices
2 medium carrots, peeled and cut into 2-inch thick slices
8-10 dried shiitake mushrooms, rehydrated
1 packet dashinomoto, dried powdered fish stock
1-2 TBL sea salt
2 TBL soy sauce
If desired, remove fat layer from broth. Place broth in large soup pot or Dutch oven, and bring to hard boil over high heat. Add reserved kombu water and return to boil.
Add kombu knots, awamori or sake, and daikon, and bring to boil. Once broth is bubbling, lower heat to medium, cover, and simmer for 30 minutes. Add cooked meat, carrots, rehydrated shiitake, dashi packet, salt and soy sauce. Continue simmering for another 30-45 minutes.
Test kombu knots: if a pointed chopstick easily pierces the center of the knots, the soup is ready. If kombu is not ready, remove carrots and daikon if you don't want these vegetables to get too mushy, and continue simmering additional 20-30 minutes. Different brands and grades of kombu will cook slower or faster, so cooking times will vary, and are dictated on when the kombu reaches the desired consistency. Consistency of the cooked kombu is also a matter of personal preference — texture can range from slightly firm (al dente) to meltingly tender. I prefer the latter, but that's just me.
Serve in individual bowls, with a separate bowl of rice, pickles, and a dipping dish of grated ginger or hot mustard. Maa-san!

Creamy Ewa Sweet Corn Soup with Kauai Shrimp

(Click on logo to learn more about the Buy Local campaign on the CTAHR site)

When you hear the words “fresh corn,” do you picture flat miles and miles of dark green stands of cornstalks in Iowa or Nebraska? I know we did, before we came to Hawaii. Now when someone mentions fresh corn, my mind immediately jumps to Ewa sweet corn, grown right down the road in the fertile Ewa Plains.
Corn in Hawaii? I know, this was a complete surprise to us too. But your first taste of these tender sweet kernels will make you a believer too. And yes, the corn is grown by the same folks at Aloun Farms who also grow those wonderful sweet onions and melons we’ve looked at earlier. If you can believe it, there is a second corn grower on this small island — in Kahuku, on Oahu’s North Shore (of surfing fame). Kahuku corn are also tender and sweet and, most importantly for Oahu, local fresh!
When produce is this sweet and fresh, we don’t usually mess with it too much — steam it or grill it, and eat it. They don’t even need butter or salt. The key with sweet corn is that it must be cooked or frozen as soon as you get it home. A corn grower in California once told me that the sugars in corn begin to convert to starch as soon as they are picked from the stalk. Sugar = tender and sweet; Starch = chewy and kind of bland.
At home, remove the husks and silk, then soak the corn cobs in a vinegar-water solution (2 TBL white vinegar for every 1 liter/quart of water), and rinse. Actually, for grilling you may want to keep some of the husks intact to use as protection from the flames (instead of wrapping in aluminum foil) or as a handle to pick up the corn. Just peel back the outer layers of the jusk (like peeling a banana) and leave them attached at the stem end. Remove the interior husks and the silks, then wash and rinse corn in their husks. Pull husks back over the corn (you can season the corn before re-husking), and they’re ready for the grill!


An alternative method, popular in Japan and here in the Islands, is to grill the corn directly over the flame, seasoning with salt, pepper and a brush of soy sauce in the last minute of grilling. Delicious! You get sweet smoke with that hint of salty shoyu. This is a favorite festival food, but easy to recreate at home, too!
We are fortunate to have more than one season for fresh corn on Oahu, and one of those seasons is going on now. With our fourth or fifth bag of corn this season, I finally decided to make something other than grilled or steamed corn. This is a thick and creamy soup that has no cream or milk — I really wanted the sweet flavor of the corn to be the star here. Its co-star is an equally sweet shrimp from a Neighbor Island — their flavors complemented each other perfectly.
Fellow blogger Pomai at Tasty Island commented on an earlier post that the use of place names (e.g., Ewa cantaloupe) not only promotes the freshness of the produce, but also increases the cachet of the final recipe to either impress one’s guests or (if you’re in the business) charge a fortune! He’s absolutely right, of course. Wouldn’t you pay $30 for that Linguine with Ewa Cantaloupe Sauce in a Waikiki hotel?!
So what did we do with the corn? Here I present you with Creamy Ewa Sweet Corn Soup with Kauai Shrimp (more on the shrimp in a later post). That should fetch at least $20 as a first course, don’t you think? The sea salad adds texture and another ocean element to the soup — we liked it a lot. The only thing I would say is next time I would cut the greens into smaller spoon-size pieces before garnishing.

CREAMY EWA SWEET CORN SOUP WITH KAUAI SHRIMP
Serves 4 as a first course
6 ears Ewa (or Kahuku) sweet corn, washed as outlined above, some husk kept intact

Peel husk back from cleaned corn to use as a handle when cutting kernels from cob. Place top of corn ear into a deep wide bowl to catch the kernels. Using a sharp knife, cut down and away from you, into the bowl. Turn ear and continue cutting until all kernels are cut from cob. Remove husks and place in large dutch oven. Repeat with all cobs. Reserve kernels (you should have 5-6 cups kernels).
Cover cobs with water, and bring to a boil. Boil for 20 minutes, and allow to cool completely.
(Optional step: I was taught to extract as much flavor from my ingedients as possible, but some people will omit this step.) When cobs are cool enough to handle, remove from water. Place one cob end in water and using the BLUNT end of a knife, press down along the length of the cob into the water to release the last bits of corn. Repeat over the whole cob, and repeat for each cob. Pour “broth” into a measuring cup, and add water to measure 8 cups of liquid. Reserve corn broth/water.
To finish soup:
2 TBL. olive oil or butter (use butter if corn is frozen or starchy)
1 small onion, minced
1/2 tsp. dried chervil
1/4 cup mirin or sake
sea salt, to taste
ground white pepper, to taste
1 lb. Kauai (or Kahuku) sweet shrimp, peeled and chopped (optional - reserve 1 tail per serving for garnish)
sea salad (chopped) or marinated sea asparagus for garnish
Melt butter in dutch oven over medium heat. Add onion and cook until translucent, about 6-7 minutes. Add corn kernels and stir to coat with butter. Cover and cook for another 5-6 minutes. Add chervil, mirin, salt and white pepper, and stir through. Cook together 10 minutes. Remove 1/4 to 1/3 of the kernels (depending on how chunky you want the final soup to be — or leave them all in if you want a smooth soup).
Add corn broth/water, and increase heat to high. Bring to a boil, then simmer for 15 minutes (add reserved shrimp tails to soup in the last 5 minutes, if using, and remove to separate plate to cool before blending soup). Taste and correct seasoning before pureeing.
Use an immersion blender to puree soup. If you have to use a countertop blender, first cool the soup, then puree, and re-heat. HOT FOODS in a covered blender can “explode” from accumulated steam and heat. I don’t recommend using a covered blender for any hot foods or drink.
Return reserved kernels to soup and return to boil. Add chopped shrimp, lower heat to simmer, and cook for 2-3 minues, or until all shrimp turn pink and firm. Ladle into serving bowls, garnish with purchased sea salad and reserved shrimp tails.

Game Day: Portuguese Bean Soup

The weather is quite dreary here this weekend and will remain so into the middle of next week, if you believe the weather guy. Our poor hibiscus looks quite weighed down by the heavy rains we got yesterday, doesn’t she?
Nevertheless, there’s a big game today at Aloha Stadium — the undefeated (11-0) University of Hawaii Warriors face off against the Washington Huskies in the last game of the regular season. The excitement on Oahu is palpable and infectious, even sweeping in sometimes-sports fans like yours truly. We casually tuned in to last week’s televised game against Boise State and then sat glued to the TV to the end. Luckily we still had Thanksgiving leftovers (ala tetrazzini) then because I was too into the game to cook.
(You can listen to today's game via the UH website here or watch on ESPN2)
This week we’re prepared with the perfect Hawaiian TV football-watching food: the venerable Portuguese bean soup. And judging by the empty Portuguese sausage shelf and dearth of ham hocks and shanks at my local supermarket yesterday, I’m guessing there are lots of soup pots bubbling away right now. This ultra-hearty spicy island classic rivals American style chili con carne in its variations and plain down-home comfort. For me the key ingredient is Hawaiian style Portuguese sausage, it’s quite distinct from its European ancestor and whatever the blend of spices they use here, it’s uniquely Hawaii. And ono. When we lived in Europe, I made this soup a couple of times using sausages (chouricos) from Portugal and those were good too, but in my heart I felt like something was missing.

The method I use for this (and most soups) is different in that I use a slow-cooker. This will require that you start at least 48 hours before you plan to serve, if you also want to de-fat the broth (which I do), at least 36 hours if you skip the cooling process. It does take a while, but I like the fact that I’m not tied to the stove making the broth or soup. In Europe we found a slow-cooker made in the U.K. that was 220-volt, and eliminated the need for a voltage-converter for a 110 volt machine. And the multiple draining and rinsing may seem like a bother, but according to Aliza Green in "The Bean Bible," this process, along with the parboiling, reduces the beans’ propensity to cause flatulence — so skip this step at your own peril! ; P
The substitution of mustard greens for cabbage is a new thing in the evolution of this soup for us — we tried this variation in a soup we had near Hilo on the Big Island a couple of years ago. The slightly bitter green brings a nice balance to the spicy meaty soup.
PORTUGUESE BEAN SOUP

Make the broth:
1 large smoked ham shank, whole
1 medium onion, peeled but left whole, or halved
4 whole cloves
4 celery heart branches, with leaves
2 large bay leaves
2 carrots, peeled and cut in large chunks
Stick cloves in onion halves or whole. Place all ingredients in 5 quart or larger slow-cooker. Cover with water, at least to 4/5 of the ham shank. Set slow cooker to High and cover. After an hour or so, check and remove scum rising to the surface. When water comes to a boil, turn setting to Low and leave for 8-10 hours, or until the meat is falling off the bone.
Meanwhile, soak 8 oz. (225g) of rinsed red kidney beans in 8 cups (2L) cool water. After 4 hours, drain the water, rinse, and cover with 6 cups (1.5L) cool water. Repeat after 4 more hours.
When the broth is done, remove the ham shank and all the vegetables. Debone and shred or chop the meat, and return to broth. You can either cool the broth overnight and remove the fat in the morning, or proceed to finish the soup as is. These pictures show the cooled and defatted broth.


If you choose to cool the soup, after de-fatting, return to slow-cooker and set on High for one hour before proceeding.
For the soup:
10 oz of Hawaiian Portuguese sausage, halved lengthwise, then sliced into half-moons
4 cloves of garlic, diced
2 cups water
1 15oz can of diced tomatoes, including juice
1 6oz can of tomato paste
1-½ tsp. paprika
1 tsp. black pepper
2 carrots, peeled and diced
1 large potato, peeled and diced
1 medium bunch Chinese mustard greens, Italian chicory, endive, or other bitter green, chopped
4 oz. (113g) dry elbow macaroni, or other small pasta shape
Drain and rinse beans. Bring 6 cups of water to boil, then add rehydrated beans and boil for 15 minutes. Leave in water until ready to use. Then drain, rinse and add to hot broth.


Over medium heat, pan fry the sliced sausage until browned, then add to hot broth. Remove the excess fat from the pan, then add garlic and cook until just fragrant. Turn heat to high and add water to pan and deglaze, add to broth with tomatoes, tomato paste, pepper and paprika. Turn slow-cooker to Low and let cook about 4 hours. Add potatoes, carrots, stem parts of cabbage, and uncooked macaroni. Cook on Low another 1-½ to 2 hours, or until potatoes and beans are tender. (Add tender green parts of cabbage last half hour.) Correct seasoning (salt will depend on type of sausage or smoked shank/hocks used) and serve with cornbread, hawaiian sweet bread, or garlic bread.
If you want to use cooked pasta or macaroni, reduce water to 1 cup, and add cooked pasta with tender cabbage greens, in the last half-hour of cooking.

The Way of Cooking: Chicken soup
But what's the one key ingredient all the commercial brands of soup will be missing? TLC, of course — love. Chicken soup is not hard. Here's an easy, foolproof method you can start in a crockpot. The only catch is, I recommend starting the day before you serve so you can chill the broth and remove most of the fat. I usually start this in the morning and let it do it's thing until evening. (Meanwhile I can do my thing and not fret too much over an open flame)
In a 5-7 quart crockpot, place:
3-4 lbs chicken backs, or a 1-2 whole stewing chicken
2 well-scrubbed unpeeled carrots, cut in half
1 large well-scrubbed unpeeled onion, quartered
green tops of one bunch of scallions
1/2 hand of ginger, sliced
Cover with water and set crockpot on High setting for 3 hours, skim as impurities form "scum" in broth.
Turn setting to Low and simmer for another 6 hours. (The long simmer is necessary to extract maximum goodness from the bones)
Remove broth to a large shallow pan to cool, then in a container to refrigerate overnight.
When cold, remove all or most (I leave about 10-15 % in for flavor) of the layer of yellow fat at the top of the broth.

Now you can do anything you want with it -- add all the vegetables you like; add chicken, seafood; add macaroni, orzo, rice noodles, rice or potatoes; add herbs or more spices; add . . . your imagination!
Here is one of our favorite chicken soups. It's a Filipino soup with green papaya — called Tinola. The papaya is supposed to be a stark white color. The one in these pictures had started to ripen on the inside, although the outer skin was still green. But it was very firm, not sweet, and stood up well in this soup. The watercress is not traditional in the original Philippine version, but I love watercress and think it adds a great flavor, not to mention all the extra nutrition from the greens. I"ve also seen this made with togan (also called winter melon) or upo (also called loofa gourd), instead of green papaya.
(Look here for a more traditional Chicken & Vegetable Soup)

CHICKEN TINOLA
(Chicken and green papaya soup with watercress)
1 large knob of ginger, julienned
1 onion, sliced
3-5 cloves garlic, chopped
8-9 cups prepared chicken broth
1 whole chicken breast, cut in half
1 whole green papaya, peeled and cut into 4-inch cubes
1 large bunch watercress, cleaned and chopped into 2-inch pieces
2 TBL fish sauce (patis)
1-2 tsp ground black pepper
sea salt, if necessary

The most important step in developing the right flavor for this soup is to saute the ginger, onions and garlic together until the onions become translucent, then slightly brown. Add chicken broth, and breast halves and bring to boil. Remove any scum that surfaces. When chicken is fully cooked, remove from broth.
Add papaya pieces, watercress, patis and pepper. When cool enough to handle, remove meat from bone, tear into large chunks and return to soup. Cook over medium heat until papaya is just tender (pierces with a fork). Taste and adjust seasoning.

Although this is a soup, you've probably guessed from the large chunks that this is not eaten directly from the bowl. I was taught to eat this with fork, spoon, plate of rice and a side dish of patis. We've given up on the tableside patis for health reasons (like all fish sauces, it's very salty with a high sodium content), but still eat this the traditional way: put some meat and vegetable on your plate and eat it with rice. You can use the broth to moisten your rice and/or drink the broth separately.
