Did you know — Korean culture
Blue crab — kkotge, literally "flower crab" for the pattern on its shell — has long been a prized catch along Korea's western coast, and kkotgetang is typically made with the crab left whole specifically because the shell and roe add flavor to the broth that fillets alone can't.
Building the spicy broth completely before the crab ever touches the pot is the real technique here, not an optional order of operations. Crab meat turns from tender to rubbery fast once it's cooked, so every extra minute the crab spends simmering while the broth is still coming together is a minute working against the texture. Getting the broth's seasoning and other vegetables sorted first means the crab only needs a short, final simmer.
Watching for the shell to turn bright orange is a more reliable doneness cue than timing alone, since crab size varies — the color change happens fast and predictably right as the meat finishes cooking, which makes it easy to catch the right moment even without exact timing.

Troubleshooting
Crab meat came out rubbery? It was almost certainly overcooked — 6-8 minutes at a simmer is usually enough once the broth is already built and hot.
Broth tastes flat despite the crab? Build the spice base fully before the crab goes in — a broth that's under-seasoned when the crab arrives won't catch up in the short cooking window left.
Vegetables still firm when the crab is done? Stagger them by how long each takes — daikon needs a real head start, while bean sprouts and zucchini can go in closer to the crab.
