The enzyme 'jamboline' present in black jamun is considered to be a boon for diabetics. That makes this rich and creamy Black Jamun Ice-cream that is made with low-fat milk sweetened with sugar substitute and thickened with 2 tbsp of cornflour instead of fattening cream..a lovely treat for the diabetic sweet tooth! It is perhaps the tastiest way to derive the benefits of black jamun although it should ideally be had raw.
