Reading a lot lately about "red peppers". Lots, actually almost all, peppers will turn red when fully ripe...jalapeno, Anaheim, Hatch, even green bell peppers. I grow most of these at home. I also grow "Italian Frying Peppers", long-ish Anaheim-shaped sweet peppers that (as their name implies) make outstanding fried peppers as side dishes, cold/marinated as salad/ on a sandwich. They should be roasted over a flame, sweated, and skinned. There is probably quite a difference between an Italian sweet pepper and a spicy Guajillo or Ancho, which also turn red when ripe. BTW, green peppers do not become more mild as they ripen to red, at least in my garden experience.
