A couple things:
Stringing them works nicely. I use a needle and dental floss (not minty!
). Dental floss is really strong and won't break halfway thru the process. Watch out--the floss does pick up some heat from the peppers, so be careful about touching it.
Freezing--if you usually seed them before use, seed them before freezing. I like jalapeno poppers, and I froze some whole jalapenos. I seeded them just before I used them and they were too hot for me--the heat seemed to migrate into the flesh from the seeds and membranes with freezing. If you don't seed your peppers before use, they can be frozen very easily, no blanching needed, just toss them into a ziplock. Works for bell peppers, too.
