Work in small batches for ease of grinding. Too much volume makes it harder to pulverize.

Place chunks in a dry blender, food processor, or coffee/spice grinder. Blend into a fine powder.

Sift through a mesh strainer to remove any coarse bits then regrind if needed.

Arrange powder in a thin layer on a baking sheet and "bake" in an oven with just the pilot light on for 10-15 minutes (or use already warm oven) to release any residual moisture. This helps prevent clumping. Let cool completely before transferring to a storage container.

Your homemade pumpkin powder is now ready! Much cheaper than store bought brands and without any added junk.
