Had an early freeze in August and had not picked all my peppers. I immediately bagged up the frozen ones and into the freezer. When I am ready to use them a few seconds under hot tap water and then immediately diced for use. Like VORTREKER says, as soon as they thaw they are mush, even from the freezer.
After all that and it didn't freeze. It might get a little colder tonight but everything is safely covered. I actually freeze a lot of peppers and just use them in salsa or sauce were the consistence isn't important. I just had no idea that 2 plants could produce so many peppers and a couple of these peppers go along way. They are so hot.
