Citric acid is a white, free-flowing powder derived from living cells in both plants and animals. This natural preservative and weak organic acid is extracted from citrus fruits and serves multiple culinary purposes. Use citric acid to enhance sherbets, pâté de fruit, poached pears, and sous vide artichokes with its characteristic sour tang. It's equally effective on vegetables, helping preserve their vibrant natural colours during cooking. Beyond flavour, citric acid functions as a powerful antioxidant, extending shelf life and maintaining freshness in your culinary creations.
