About this dish
Kkotgetang is a classic Korean spicy crab stew made with 600g of whole blue crab simmered until the shells release their full flavor into the broth.

Gochugaru and a touch of doenjang season the liquid with heat and fermented depth, while radish and zucchini turn sweet as they absorb the crab-infused stock. Two Cheongyang chilies push the spice level higher, and green onion adds a fresh finish. Picking the crab meat from the shell while sipping the hot, briny broth is half the enjoyment. Spring blue crabs are prized for their fuller flesh, making that the ideal season to prepare this dish.

Instructions
Read the steps as a cooking flow: prep, heat, seasoning, doneness control, and finish.
- 1Heat
Scrub 600g of blue crab under running water with a brush, especially around the legs and shell joints.
Remove the apron and gills, cut the bodies in half, and let excess water drain before cooking.
- 2Heat
Slice 150g of Korean radish thinly so it softens quickly, and cut 80g of zucchini into 0.5cm pieces.
Slice the onion, green onion, and 2 Cheongyang chilies before the pot starts boiling.
- 3Control
Put 900ml of water, the radish, and 0.5 tablespoon of doenjang in a pot, then dissolve the paste fully.
Bring it to a strong boil over high heat and cook about 7 minutes until the radish looks partly translucent.
- 4Control
Add the prepared crab, 1 tablespoon of minced garlic, and 1.5 tablespoons of gochugaru.
When the broth returns to a boil, lower to medium heat and simmer 10 minutes, until the shells turn red and the broth smells rich.
- 5Control
Add the zucchini, onion, and Cheongyang chilies, then simmer 6 more minutes.
Once the zucchini edges soften, stir gently and only as needed so the crab meat does not break apart in the broth.
- 6Finish
Add 0.5 stalk of sliced green onion and simmer for 2 minutes to finish the aroma.
Skim off surface foam, check that the broth is not too salty or harsh, and serve the stew while hot.
