Either peel off the zest of citrus fruit in wide strips with a vegetable peeler, or grate finely. Remember to remove zest before cutting and squeezing - it's almost impossible afterwards.

Pare the zest from the limes (or other citrus fruit) in thick strips using a vegetable peeler, then cut the strips into thin sticks. Put the zest in a small saucepan and cover with cold water.
