Red cayenne chile peppers I've picked earlier this summer have dried nicely sitting on a plate in my kitchen. It takes a few weeks. Since I have a big batch of them now, I strung the chiles on wire and hung them up. I just treaded the peppers on 18 gauge galvanized wire and bent it into a loop for hanging. I went ahead and hung a few of the thicker skinned jalapeños and round chiles too. Just to see if they'll dry. They look very decorative.
