Unusual ingredients which are common in your cooking

[jfk]

Tanqueray has started running ads for their new Rangpur lime gin. I grow Rangpur limes and frequently use them in my cooking, though I've never seen them anywhere else. (Note: the add shows them as green. They are very, very orange, both peel and flesh as they as a sour Mandarin, not a true lime.)

As such, I was wondering what can be found in the various TLDR kitchens, pantries and gardens and the uses you have for the various items.

The Rangpur limes have an almost pithless peel, and is an excellent candidate to be used dried. The juice is very tart and is an excellent addition to many sauces. I frequently add thinly sliced Rangpur limes to a pot of black beans.

Other unusual citrus I grow and use in cooking include: Kalamansi, varigated pink lemons, Kaffir limes and Chinotto sour oranges.
