We have preserved our finger lime fruit in a similar way that is commonly used to preserve lemons. We use salt, water, clove, cinnamon, chilli and bay leaf in small amounts to provide some complexity. It can be used in exactly the same way as preserved lemons and has a distinctive citrus flavour. We find it fantastic on a salad, in cous cous, casseroles or added to stuffing for roast chicken. Use anywhere where a hint of citrus is desired.
