A member of the mackerel family, tuna are mainly found in the world's warmer oceans. They can grow to a huge size (up to 700kg) and their meaty flesh is distinctively flaky and firm with a rich, strong flavour, the consequence of its comparatively high oil content.
Tuna is mainly sold as steaks. It dries out quite quickly, so should be cooked very briefly over a high heat; marinated before cooking; or simmered in a sauce. Approximate weight 165g.
