Citric Acid (Sour Salt)

Citric acid crystals are the powdered, crystalline form of citric acid and add tartness to food in place of lemon juice. They are used as a preservative and acidulant in pickles, syrups, and preserves. Because a small amount adds strong tartness, measure carefully.

Where It’s Used

“Add a pinch of citric acid to the syrup to keep it from crystallizing.”
