Shishito peppers are mainly mild in flavor, but one in ten may have a little heat. The Japanese name for these is shishi which means lion. The tips of the peppers are puckered and looks a bit like a lion head.
Farmers markets and some grocers may carry these. Look for peppers with wrinkles and twists, a narrow shape and about three inches long. They are usually green, but may have red and orange color also. Store refrigerated in a paper bag up to two weeks.
Grill, roast, or sauté to blister the skin with a little vegetable oil, season with salt or other seasoning and serve immediately.
