What is gejang?
Gejang(게장) is a traditional dish that’s made by marinating raw crabs in soy sauce. Historically, a very salty soy sauce brine was used as a way of preserving the crabs for a long time. Nowadays, gejang is enjoyed for its deliciously savory taste, so fresh crabs are marinated in a mild soy sauce-based brine and usually eaten within a few days. This modern version is enormously popular in Korea. The soy sauce-basedgejangis also calledganjang gejang(간장게장) to distinguish it from a spicy version, which is another modern concoction, calledyangnyeom gejang(양념게장).
In my family, two of us are big fans ofgejang. When I was pregnant withmy first child,gejang was whatI craved the most. Interestingly, my first born lovesgejang.During one visit to Korea, he waited45 minutes in line outside on a hot summer day to eat at a restaurant well known for itsgejang.I wonder if his love forgejanghas anything to do with my pregnancy cravings.
Gejang is eaten with a bowl of rice. Koreans even refer to this dish as a “rice thief” (밥도둑). Your bowl of rice will be gone in no time as you enjoy sucking the flavor-packed crab meat out of the shell. Be sure to leave a spoon or two of rice to mix with the roe and tomalleyin the top shell. The crab infused brine is also delicious mixed with the rice or as a sauce for other dishes.
How to make gejang
In Korea,gejangis most commonly made with a crab species called,kkotge(꽃게), akahorse crab. The Korean name literally translates into “flower crab”. Here on the east coast of the U.S., we have blue crabs. I started thisgejangpost earlier in the summer, when the peak season for Chesapeake Bay blue crabs had just started. But even now, I am still able to find fresh female crabs with roe. We Koreans prefer female crabs for makinggejang,butyou can also use male crabs, especially in the fall when they are fat and bountiful. As is the case with the consumption of any raw seafood, be sure to use only the freshest crabs.
The method for makingganjanggejangis relatively simple. Dealing with the live crabs will be your biggest challenge. However, it’s very common in Korea to freeze live crabs since fresh crabs degrade very quickly. I always put them in the freezer for a while for easier cleaning.
To make the brine, Korean cooks tend to use a wide variety of aromatic ingredients. The goal is to eliminate the raw, fishy taste while enhancing the flavor of the crabs at the same time. The brine should be flavorful, but not overpowering and too salty.
Ganjang Gejang (Raw Crabs Marinated in Soy Sauce)Side Dish
- 5 medium fresh blue crabs or kkotge about 2 pounds
For the brine:
- 2 cups soy sauce
- 1/2 cup rice wine or mirin
- 6 cups water
- 3 tablespoons sugar adjust to taste
- 1/2 medium onion roughly sliced
- 5 - 6 plump garlic cloves
- 3 - 4 thin ginger slices about 1-inch round
- 1 piece dried kelp dashima (about 5-inch square)
- 1 small apple roughly sliced (or 1/2 small Korean/Asian pear, if in season)
- 1 bay leaf
- 1/2 teaspoon whole black peppers
- 2 to 3 small dried whole red chili peppers
For the garnish:
- 2 - 3 green and/or red chili peppers thinly sliced
- a few thin onion slices
- 3 thin lemon slices
- Put the live crabs in the freezer for an hour or two (longer is fine as well), unless you are comfortable with handling live crabs.
- Meanwhile, bring all the marinade ingredients to a boil over medium high heat. Reduce the heat to medium low, and continue to boil, covered, for about 20 minutes. Remove the kelp after about 10 minutes of boiling. Strain the brine. Discard the fruit and vegetables. Cool completely, and then refrigerate until ready to use.
- Clean each crab thoroughly with a kitchen brush. Drain well in a colander in the fridge.
- Place the crabs in an airtight container or jar. Add the chili pepper, onion and lemon slices. Pour the brine over the crabs. Make sure all the crabs are submerged. Weigh them down, if necessary, with a small bowl or plate that fits inside the container. Refrigerate.
- After one day, strain the brine into a pot (and put the crabs back in the fridge). Bring the brine to a boil over medium heat, and boil for 3 to 4 minutes. Wait for the brine to completely cool, and then pour it back over the crabs. You can skip this process, but it enhances the flavor of the brine and helps the crabs to last longer.
