Korean food isn't just about barbecued beef and kimchi. It's full of rich soups, like spicy tofu stew, or sundubu jjigae. Sundubu means soft tofu and jjigae means stew. I've been wanting to make spicy tofu stew since I visited South Korea last October.
Stews are made in ddukbaegi, or earthenware pots, like the one pictured below, or they're made in dol sot, or stone pots.

I had really flavorful spicy tofu stew at a hospital cafeteria in Seoul.
I never made this dish before. I actually don't remember if my mom made it for me. After looking at several recipes online and in a cookbook, I figured out a recipe that fit my own tastes. When I made the soup, I couldn't believe that it actually tasted
really good. It was spicy hot, but not overly spicy. It was filled with tofu and clams and kimchi and scallions.
It's the ingredients that make the stew tasty.

Left to right: Cabbage kimchi, salted shrimp and kochu karu, or Korean red pepper powder.
Kimchi is made up of spicy, fermented vegetables. Salted shrimp is used to make kimchi. It's spelled saewoojeot, or saeujeot in Korean. Kochu karu is the Korean version of cayenne pepper and it is also used to make kimchi and flavor dishes.
Tip: Salted shrimp has a very strong smell. As soon as you bring some home, I'd put the salted shrimp in a jar that seals really well.

Alternate spellings: soondubu jjigae, soondubu chigae
Serves 4-6
Ingredients:
For the dashi stock:
two pieces of dried kelp (roughly 3 by 5 inches each) Size is not crucial.
dried anchovies, each anchovy should be 3 inches long
8 cups water
For the stew:
1/3 pound pork belly for the soup (If you bought a pound of pork belly, you can cook all of it or save it.)
2 tablespoons kosher salt
2 tablespoons sugar
kochukaru, or Korean red pepper powder. Substitute: Red pepper flakes or cayenne pepper
1 dozen littleneck clams
1/2 cup kimchi, chopped
sesame oil to taste
2 garlic cloves, minced
1 (14-ounce) package silken tofu
1/2 teaspoon salted shrimp (optional)
4 scallions, chopped into the size of matchsticks
1 jalapeno pepper, sliced thin cross-wise
2 eggs
Start making the rice in your rice cooker. Clean clams in a large bowl of cold water. Scrub them until they no longer feel gritty. Get rid of any clam that is chipped on the mouth and shows a hole.
Dashi stock:
Heat a pot of water until simmering. Rinse the dried kelp. Turn off the heat and drop it in the water. Let it steep for 10 minutes. Then discard. If you let the kelp sit in the water for too long, it will make the stock taste bitter. Turn on the heat until simmering. Then drop in 20 dried anchovies. Bubbles will form around the anchovies. Simmer for 20-30 minutes. Taste the stock to make sure it really has the flavor of the anchovies. Strain the stock. Set it aside.
Pork belly:
You just need one long, thick strip of pork belly for the stew. Mix together the salt and sugar. Rub the mixture all over the pork belly. If you have the time, let the pork marinate in the refrigerator for 5 hours. If not, season the pork with salt and sugar. Cut into bite-size pieces. Add oil to a heated pot. Use a Dutch oven or cast-iron pot. Sear the pork belly in the pot. When the pork belly is almost fully cooked, set aside.
Add stock and chopped kimchi. Season with sesame oil and garlic. Bring to a boil.
Before you add the clams, wash each one again under the faucet to get rid of grit.
Add clams to the stew. Add silken tofu. The clams are cooked when they open. Add salted shrimp (optional). Season soup with salt. Add chopped scallions and sliced jalapeno peppers. Add the pork back into the soup. Drop one egg at a time into the pot. When the eggs are cooked, the soup is done. Serve with rice.
