I use a cheap ($40) Oster dehydrator from Walmart. Cut peppers in half, put in dehydrator seed side down, they are done when pods crack. If the pods bend without cracking they are not done. Like elcap, I use a coffee grinder ($15 at Walmart) to grind into powder under my exhaust fan. Let it settle a minute or two before opening grinder to prevent breathing in powder. Make your own seasonings/rubs by mixing with garlic powder, onion powder, or herbs. Ground scotch bonnet, ground thyme, and ground allspice makes the killer jerk rub for jerk chicken. I haven't used black pepper in over a year. Honemade spices are waaaaaay better. Good luck.
