Simmer


Pour in 6 cups of anchovy broth (or 6 cups of plain water with 2 broth tablets), then add the radish and the blue crab top shells.
We will boil the crab shells first to draw out their rich flavor into the broth, and remove them halfway through.


Add 1 tbsp of doenjang (Korean soybean paste) (use 1/2 tbsp if using homemade doenjang) and 1 tbsp of gochujang (Korean red chili paste)...


Add 2 tbsp of soup soy sauce (guk-ganjang) and bring to a boil.
Once it boils, lower the heat to medium and let the radish cook thoroughly.
Now take out the crab shells and discard them.

Add the prepared blue crab body pieces.



Next, add the seasonings: 2 tbsp of gochugaru (Korean chili flakes) and 1 tbsp of minced garlic...
Add the soybean sprouts as well, letting the crab and sprouts cook through while the seasonings blend into the broth.
Crab cooks quickly, so do not simmer it for too long if you want to enjoy tender, chewy meat.


Taste the broth, and if it needs more saltiness, adjust with 1 tbsp of sand lance fish sauce or salt...
Add the onion, green onion, chili peppers, and a little ground black pepper, then bring to a quick boil until the vegetables soften.


Add the ssukgat at the very end, turn off the heat within 30 seconds, and finish.
Complete

The blue crab stew is complete.


Because it is in-season fresh blue crab, the meat is tender and wonderfully chewy.
The broth infused with crab flavor is remarkably refreshing and deeply savory.
Prepare a delicious dinner and enjoy your meal.
