How does the texture of pouting generally compare to flatter fish like sole?
Tends to have a somewhat softer texture
When comparing the textural characteristics of bottom-dwelling white fish, pouting occupies a specific position within the spectrum, particularly because it belongs to the cod order. Relative to flatter fish species, such as sole, pouting generally exhibits a somewhat softer texture. However, this softness is not extreme; it is described as being firmer than some of the very delicate varieties within the whiting family. This moderate firmness means that while it is not as robust as a dense, flat fillet, it still holds together reasonably well, although cooks might need to employ slightly gentler handling or shorter cooking times to prevent it from becoming too fragile during preparation.
