The process is simple: no measuring or grinding, cooking or dehydrating.
Zest whatever citrus fruit before you use it and toss it with a little salt. Be sure to mix the zest well with salt right after zesting so it does not have time to develop mold. Then let it sit until you use it in a recipe or add more to the bowl. Citrus salts will brighten up any dish: sprinkle on cookies, scones and muffins; toss it in soups, stews and curries; or use a generous handful to salt a chicken or pork loin before roasting.
Citrus zest (preferably from organic or unsprayed fruit)
