How to prepare lime leaves for cooking

Remove the thick centre vein from the leaves. This makes them easier to slice, and the tough centres can be too chewy to eat.
Stack a few leaves, then use a sharp knife to thinly slice lengthways. This is easier and quicker than cutting them individually.

Freeze shredded lime leaves in a sealable plastic bag for up to a year. Add fresh or frozen leaves directly to curries or stir-fries.
