Chilli crab is a sauce dish as much as a crab dish: tomato, chilli, egg, and aromatics should cling in a glossy coat you mop with fried man tou. At home, start with a cooked mud crab from a good market if live crab is intimidating.
When you travel, compare sauce balance on our Singapore seafood shortlist — spice should warm, not obliterate, the crab.
