Seafood jjim near Asan Terminal for spice-shy eaters: Sinseong Agujjim

In short

Sinseong Agujjim Asan Branch (신성아구찜 아산점) is a monkfish and seafood jjim (braised seafood stew) restaurant in Mojong-dong, Asan, near Asan Terminal. The writer's husband can't handle much spice but wanted seafood jjim, so the two of them ordered a small seafood jjim at spice level 1 and finished with fried rice. The pot was packed with octopus, squid, abalone, crab, mussels and shrimp, and the sauce was mild yet kept them coming back for more. Because Sinseong Agujjim Asan Branch lets you choose a spice level starting from level 1, it's a good seafood jjim spot to visit with someone who struggles with heat.

Sinseong Agujjim menu and tips for adding extra seafood

The add-ons for the seafood jjim were pretty generous as well: you can add monkfish, squid, octopus, fish roe, milt, odeungi (sea squirts) and more, picking the ingredients you like to make it even more filling. For meals there were steamed rice, fried rice, flying fish roe rice balls and a kids' pork cutlet, and there were also giant fried shrimp, udon noodles and ramen noodles that go nicely with the stew.

One catch: they say the seafood add-ons need to be put in with your first order so everything is timed and tastes right, so decide before you order. Two of us went, and we ordered a small seafood jjim and fried rice.

The deep flavor of the seafood itself comes out in the spicy sauce, so the seasoning doesn't just sit on the surface, and it's really delicious. Picking out the plump seafood and adding crunchy bean sprouts makes for a festival of textures. Dip it generously into the special sauce and the seafood's savory umami comes through even stronger.
