Lemon sole is increasingly being promoted as a guilt-free fish for the modern consumer.

As one of the species of fish around the Cornish coast that are not subject to catch quotas, lemon sole appears on the Marine Conservation Society's 'fish to eat' list.

In Cornwall the abundant species is caught mainly by inshore 'day-boat' trawlers working from ports such as Mevagissey, Looe and Polperro. At its freshest, lemon sole has attractive markings and is slimy to touch. Not overly juicy, the fish is soft on the palate and is said to have something of a breadcrumb-like eating quality.

Lemon sole is most abundant in UK supermarkets between April and August when the fish is in season, with all major supermarkets and fishmongers stocking the species.

UK-sourced fish is not available during the winter months, but frozen imported lemon sole is brought in from Iceland, the Faroe Islands and other fishing nations.

It is a fish that can be cooked very simply and is at its best grilled whole with a squeeze of lemon and served with seasonal new potatoes, according to industry body Seafish.
