Are you wondering about the skin on just a hatch , or in general ?I wonder if even the skin gets so dried that it grinds to powder easily.
This is an end of season assortment I did a couple years back . Ended up with a smokey sweet powder with a heat that sneaks up on you . I ground the peppers whole . Seeds , membranes and skins . Some were smoked . I guess you could sift it out and regrind , but I like it like this .

Carolina Reaper powder I got from Richie . Good stuff . I don't think he skinned these . I know I wouldn't want to . I'm not gonna even open the bag to take the pic . Lol .
