Tangerine is a small, deep-orange mandarin with a thin, loose rind and sweet segmented flesh.
The perfumed peel does more work than the juice. Squeeze a piece of zest over a finished drink and the oil spreads across the surface. Juiced on its own it is too soft to hold a sour together, so add a little lemon.
Clementine or satsuma
Swap them in one for one. They are just different types of mandarin, usually seedless.
A solid backup. By weight, one large navel orange replaces roughly a mandarin and a half, though it is slightly less sweet.
Up to about four weeks somewhere cool but not cold. A domestic fridge runs colder than mandarins like, and chilling injury shortens their life, so avoid the coldest shelf. Squeeze to order: in some varieties the juice turns bitter as it stands.
