Recipe tips Three-cornered leek (also known as wild leek or onion weed) are similar to wild garlic, with a milder flavour. They can be foraged in the UK between late autumn and spring – you'll find them in dappled shade, along hedgerows and roadsides. Make sure you know what they look like before picking, they have slender green leaves, white flowers and a strong allium smell when crushed.
