if you want to dry the frozen peppers, thaw them in a colander to allow all the excess moisture to drain away. Or just be prepared for a whole lot of pepper juice in your dehydrator.
pepper jellies probably wouldn't work too well with frozen peppers unless they are well drained. I have not made jelly out of frozen peppers so i can't speak from experience. Dried chiles work in pepper jellies.
Frozen peppers probably wouldn't work for
candied peppers (different than pepper candy). If you have a bit of time and want to try something different, try making candied peppers. I like using ripe peppers better than green peppers. Super fun! and super easy, just takes a bit of time.
Pickling is easy and quick. Several thread here on that topic, pickling should definitely be done with fresh peppers. If you have room in your fridge, you can cold pack the chiles in a vinegar brine and just let 'em sit.... I make a really popular pickled pepper medley with peppers (usually jalapeno or habanero) onion, garlic, carrot and cauliflower. You can pickle the peppers now, just get 'em in a gallon jar in the refer, and when you have time, add more vinegar brine and the other veggies and let 'em pickle up.
Lots of people have successfully fermented with frozen chiles.
Frozen chiles work just fine in any cooked/bottled sauce.
Have Fun and Enjoy the Bounty!!!
