Barberries are an important ingredient in Iranian cookery, and you're most likely to find them in a Persian or Moroccan restaurant. Increasingly, they are now available to purchase as a dried product. Barberries keep very well and rehydrate within 10 minutes and can be added to slow cooked dishes or rice pilafs. Traditionally, they were highly valued for their high pectin levels and used extensively in jam and jelly making. Barberries have a wonderful tart lemon tangy flavour which adds zest and tartness to any dish and their vibrant red colour gives a warm hue and richness to dishes.
