Fruits, frozen or canned Status: Canned, jarred and frozen fruit are acceptable without certification if (a) they only contain fruit, sugar, ascorbic acid, malic acid, and/or citric acid, and (b) are not from Israel or China. Accordingly, those which contain flavors, colors, carmine, fruit juice, grape juice, or other sensitive additives, must bear a reliable kosher certification. Canned olives are an exception. See Olives. Non-organic frozen raspberries, blackberries, and mulberries can only be used if pureed. Frozen Strawberries are also an exception. See Strawberries, frozen
