When served El Torito's flautas with this dip, I damn near keeled over with pleasure. It's complex without being difficult , unless you count how hard it can be to find Japanese peppers. If you can't find them, I'm sure you could sub something similar. These are mild, thin-skinned, 3-inch-long peppers with wrinkles running down the length of them and a blunt tip. I found them in a large Asian market's produce section on a plastic-covered styrofoam tray. Though I roasted and dehydrated them, I don't think the drying is necessary. Roasting whatever pepper you use, however, is crucial to the flavor of the dip. My husband and I both agreed this is a versatile dip and we'll be using it on hamburgers tonight. Hope you enjoy it as much as we did!
