Fruit powder is dried fruit that's been finely ground. Fruit powder can be used in place of artificial flavoring to flavor just about anything. However, fruit powder truly shines in desserts where the moisture balance is very important.
Any dehydrated fruit that has not been sweetenedbe sure that the fruit is fully dehydrated with little to no moisture remaining
Freeze the dehydrated fruit overnight.
Blend the frozen fruit until it turns into a powder. (It helps if you have a blender with some kick. I heart my Vitamix for tasks like this.
For reference, two pounds of fresh strawberries and one pound of sliced/frozen rhubarb yield 1 1/4 cups of fruit powder after being dried and blended.The powder may end up slightly clumpy. Be sure to sift before using in recipes that require a fine texture.
