Most of my dried superhots end up as powders. The nice thing about powders is that you have control over the heat. So let’s say, for instance, that you are making a pot of chilli and want to heat it up. You add 1/8 teaspoon of powder, give it a stir, wait a few minutes and taste it. If it’s good enough you’re all set. If not, keep adding until it’s to your satisfaction. I have a smoothie maker with a nut grinding blade that turns the peppers, seeds and all, into powder in seconds. If I want flakes I use a mortar and pestle. Powder is also an easy way to make flavored salts. Put some table salt in a bowl, add some powder, mix it up and put it in a salt shaker. Couldn’t be easier.
It’s a sad day for my brother when he runs out of the season’s homemade cayenne pepper - he loves the stuff.
I like “hot” for the most part so your hot pepper powders sounds really good.
