Originally derived from citrus fruits, the so-called "sour salt" is used as a flavor enhancer and a preservative. For the homecook, use it in fruit preservation, to emulsify ice cream, or to make soft cheeses like ricotta or paneer. It's also a useful replacement for lemon or lime juice when you don't have any on hand, but you need that sharp acidic brightness.
