While salmon might not be a traditional choice for Korean lettuce wraps, it is a delicious and fast one. Start by coating cubed salmon in vinegar and ssamjang — the salty-sweet-spicy sauce that’s also dabbed on the final wraps — then broil the salmon: The direct heat of the broiler mimics the sizzle of Korean barbecue, and broiling skin-side-up ensures the fat renders, the skin crisps and the meat doesn’t dry out. Eat the cubed salmon in a lettuce leaf with rice and more ssamjang, plus any other condiments you like. Fresh cucumbers and radishes and spicy raw garlic and kimchi play well with the silky, rich fish.
