Shell

Crab shell is the carapace and claw shells used for stock, butter, and bisque—roasted until sweet and coral-coloured, then simmered. Residual meat and tomalley traces build body. Roast shells with oil, simmer with aromatics, strain hard. Freeze stock in small lots; it is the backbone of classic crab soups.
