Crab
Flavour Profile
Sweet, delicate, and briny. White meat is lean and subtle, while the brown meat found in the body is rich, buttery, and intensely savoury.
It carries a distinct 'ocean' scent that should be fresh, never 'fishy'.
Health Benefits
Vitamin B12 for energy and a bit of selenium for keeping your cells sound. It's also packed with protein. The brown meat is where much of that flavour and fat lives, and it's also where you'll find more of these nutrients. You're welcome.
Buying Tips
Look for crabs that feel heavy for their size; lightness usually means they haven't filled out their shell after a moult. If buying whole and live, they should be active and feisty.
If you're buying pre-picked meat, look for 'dressed crab' or sealed tubs. Ensure the meat is pearly white (for claw and lump) or rich ochre (for brown meat) with no greyish tinges.
Storage
Freshly cooked crab meat is highly perishable. Keep it in the coldest part of the fridge and eat it within 24 hours.
If you have leftover shells for stock, freeze them immediately. You can freeze picked crab meat, but the texture will lose some of its refined snap once thawed.
Cooking Uses
Pot-boiling is the classic start, but steaming keeps the meat sweeter and less waterlogged.
Use the delicate white meat for salads, crab cakes, or elegant pasta dishes with chilli and lemon. Use the rich brown meat to thicken sauces or spread directly onto hot sourdough toast with a pinch of cayenne.
Don't bin the shells. Roast them and simmer with aromatics to make a world-class shellfish stock or bisque.
Forkin' Food Theory
Most people focus entirely on the white leg meat, but the real depth is in the brown meat.
Brown meat is essentially the crab's liver and pancreas. Because it's high in fat, it acts as a natural emulsifier.
If your crab pasta sauce feels thin or broken, whisking in a spoonful of the brown meat will bind the butter, oil, and pasta water into a silken, creamy sauce without needing a drop of actual cream.
