The resulting powder can be sprinkled on things like chips(crisps), popcorn, etc.
Step 1: Ingredients/Equipment Needed
Then you'll need to decide on what oil/fat you want to use. Bacon drippings are good. If you want to use butter, you'll need to clarify it by melting it over very low heat until it starts to bubble and foam. Then you skim off all the foam so you're left with a bright yellow fat with no white milk solids and reduced moisture content.
If you're making savoury powders, you'll need salt. Even with the sweeter powders a tiny bit of salt will help bring out the flavours better and compensate for the additional, but slight, sweetness of the maltodextrin.
For equipment, you just need a few bowls, a small whisk, a spoon, and a sieve.
You'll need a pan or a pot if you're going to melt the fat out of bacon or clarify butter.
