Sometimes sourcing and prepping a whole crab (or, depending on how many people you’re serving, several whole crabs) is kind of a big ask. If that happens, just take the easy route and buy pre-cooked crab, which is an excellent option if you’re short on time. Although fresh crab does have a more vibrant taste and firmer texture, Xiaojun Guo says, “Pre-cooked crab is convenient and retains much of the flavor. When buying pre-cooked, check that it has been refrigerated properly, and avoid any with a fishy or sour smell, which indicates spoilage.”
It’s also an easy route for beginners just learning to cook with crab, says Anthony D’Angelo, 5th generation co-owner of Samuels Seafood Company. He recommends you buy “pre-cooked crab meat like Blu™ Crab, which comes in 1-pound containers, allowing you to enjoy it directly or mix it with ingredients like mayo and breadcrumbs for dishes like crabcakes. Simply bake or fry for a quick meal.”
D’Angelo notes, however, that you’ll want to reserve this option “for dishes where the crab isn’t the star ingredient but adds flavor.” In fact, “For recipes like salads or dips, pre-cooked can be preferable. However, for dishes where the crab’s freshness is crucial, like steamed Blue Crab, live crabs are ideal.” If you’re not certain, he says, just ask your fishmonger what will work best.
