As a culinary ingredient, citric acid is used in cooking to add a sour flavour or adjust the acidity of a dish and is commonly used in canned fruit preserves, to ensure the fruit retains its freshness. It also helps balance the acidity of dishes without the vinegary or lemony flavour and it’s an excellent way to add a lemony tang to dishes. Add a few shakes of this sour salt to rye bread or sourdough or sprinkle a small amount on glazes or frostings for a tinge of acid.
