I have had very good results using the microwave to remove a large part of the moisture from the chiles before oven drying them. I chop the chiles into pieces about 1/4" to 3/8" square (ok, ok, I don't use a mitre, I'm not that AR)and microwave them on defrost for 5 to 10 minutes, checking every minute or so. Then I finish drying them in a 200 degree oven for about an hour. The Habs I've done like this get a nice roasted flavor to them and the heat is retained well. One caution, though. Our microwave is at eye-(nose and throat)level and my wife, a fledgling CHer walked by the microwave during the initial stages of drying and was gassed into a coughing fit for several minutes. I'm sure the thinner walled chiles would take much less time and the thicker walled ones more, the key is to keep an eye on them during the process. Good luck! Doug
