I voted Jalapenos and Cayennes although it would have been better labelled "Jalapenos, Anaheims, and Caribbean Reds" to more aptly describe my favorite peppers. Jalapenos are so good either green or red and can be used in so many ways. My favorite is to take big, corked, red pods and smoke them with pecan and then dehydrate. I freeze them and make chilpotles in adobo throughout the year.
Anaheims are the premier stuffing pepper in my opinion and I love their taste. They're also great for cooking in a variety of dishes.
Caribbean Reds are my favorite of the chinense varieties. I love to smoke them and make powders. They're also good on ham sandwiches. Finally, I make CR Apricot pepper jelly each year and give out for XMAS presents. They also are perfect sliced in Nam Pla (fish sauce) as a side for Beef Bai Kao Pow or other Thai dishes.
I'm getting hungry...
