Rainbow trout meat is mild, with a delicate, nut-like flavor. The flesh is tender, flaky and soft. The flesh of rainbow trout is white, pink or orange. When the meat is cooked, it has a delicate flake and the color pales. Trout feed can contain pigments to produce desired flesh colors. The fillets need to be firm, resilient and have a fresh appearance. The skin of the rainbow trout should be dark, shiny and have a slippery feel.
