Acidulated water

A mixture of cold water and a small amount of vinegar, lemon or lime juice. It's used as a soak to prevent discoloration of some fruits and vegetables that darken quickly wen their cut surfaces are exposed to air (pears, apples, avocados, artichokes). It can also be used as a cooking medium. Acidulated water can be made by combining 1.5 tablespoons vinegar or 3 tablespoons lemon juice or 1/2 cup white wine with 1 quart of water.
