Yes, you can dry them in the oven, but I don't do that personally, so I can't give you a time and temperature. Now if you mean actually on top of the stove, I would imagine that would work, but have no clues on how well it would work. Mmmm ghost peppers, put them in a smoker grill at about 200 for 4 hours and use something good like pecan wood, and then finish drying in the oven, and you will make some great smoky tasting powder that tastes like it belongs when you put it in baked beans or BBQ meat.
Neither my pepper website, or my cycad jungle website has automatic purchasing because I want to give personal service and I charge the direct cost of shopping instead of charging an over priced charge that is done automatically. People just email me. Tom
PS, Franklin, if it is going to be a while, and if you like, send me a private message and give me your address and I can send you a sample packet of smoked ghost powder in a regular envelope for free, just to get a good taste of it.
