*Can I use this method on other peppers?
It turns out that you can. And pretty easily, too. You'll have to make adjustments to the timing for smaller or more thin-skinned varieties but any pepper with benefit from a smoky, roasted flavor. And speaking of thin-skinned peppers, you might find that those varieties don't even need to be peeled. Use your own judgement but you'll likely find that some smaller ones are tender enough to leave as-is.
