The lime is a small, green citrus fruit used almost in its entirety for its juice, zest and leaves. Smaller and rounder than a lemon it has a stronger, more bitter taste.

Kaffir lime, darker and more knobbly than the ones found in supermarkets and greengrocers, is widely used in south east asian dishes, particularly Thai recipes where the juice is one of the main elements of dressings for salads and noodles and the shredded leaves flavour a wide range of savoury dishes.

Lime juice can be squeezed into cocktails or sprinkled over finished dishes to enhance their flavour; it effectively 'cooks' raw fish in ceviche.

Key lime pie is a famous dessert from Florida traditionally made with a special variety called Key limes.
