Have you heard of Hatch chiles? They come from an area of southern New Mexico near the Rio Grande River, around the town of Hatch. So it's a geographical name, not a variety of chile pepper. The harvest is in - and St. Louis has some. They're at the two Lucky's Markets, and I write about it here. These batches are one step up from the mild variety, and they're being roasted on the spot, an old New Mexico tradition.
Good stuff, and lots of ways to use them.
