In our experience, most supermarkets do a decent job of stocking a variety of fresh hot chiles, but identifying them is another thing. They’re often mislabeled, and sometimes they’re just in an anonymous jumble. On this page are some of the varieties that commonly appear in markets. Fresh chiles should be smooth, firm, and glossy. Some jalapeños may have “scar cracks” at their stem ends, but other varieties should be blemish-free.
