Among the sweeteners less rich in calories, perfect for preparing a large number of desserts, maple syrup is certainly found: this Canadian specialty, whose origins can be traced back to the typical uses of the Iroquois Indian tribe, in the past was prepared in the form of sugar crystals, the purpose of which was to essentially replace cane sugar. Maple syrup is also well known for its notable virtues for human health, starting from its antioxidant properties, as well as its high content of potassium, iron, vitamins and malic acid.
