Here's a quick way to roast peppers... we've done it several times and it works quickly! I let hubby handle the MAPP torch, though.. I haven't tried it myself.
However, you need a propane or MAPP torch to do it.
Hold the pepper with tongs by the stem, if possible, or place it on a fireproof surface (bbq grill, maybe?). Run the torch over the surface of the pepper until the skin is blackened, rotating the pepper as needed.
Once the skin is blackened, put the pepper in a ziplock bag, seal it, and let it sit until cool enough to handle.. rinse under cold water, peeling off the blackened skin.
At that point, I sliced/chunked them, and sauteed them a bit in a skillet with olive oil and some onion.... so yummy!
When we buy Hatch green chiles in the fall, the grocery store has a big roasting barrel they keep turning, and that roasts them over a fire.. so yummy then!
