Banana powder tastes great in foods but also packs substantial nutritional benefits. It can be used to add sugar naturally, permitting you to use 10-20% less white sugar in your cooking. Banana powder contains an abundance of vitamins, minerals, fiber, and healthy fats. Since it contains pectin, it works well as a thickening agent too. Note: 1/3 cup banana powder + 2/3 cup warm water = 1 cup banana puree.
