I do not have a dehydrator but want to know the propper way to dry peppers. Most importantly nagas, habs, and cayan. I live in southern california. I will be drying these for making powder. Will the powder keep in a shaker bottle, or should I put it in the fridge/freezer? Any painless methods for gringing them up? I have a mortar and pestle. Also, will whole peppers keep in the freezer if I throw them in a ziplock?
