400 grams of purple potato

Method for making purple sweet potato powder

Steam the purple potato for 20 minutes (without peeling)

After the purple potato is steamed, peel it by hand, put it in a bowl, and press it into mud with a fork.

Spread the mashed purple potato on a non-stick cloth, push it away with a spoon and cut it into thin slices.

Preheat the oven at 90'C and dry it for 2-3 hours, and the time is adjusted according to the moisture and thickness of purple sweet potato paste. When the purple potato paste is crisp and thin, the whole piece can be separated from the non-stick cloth, put into a blender, ground into powder, and put into a fresh-keeping glass bottle, which can be stored for several months.
