After my last purchase of Pasilla de Oaxaca peppers, which was unsatisfactory because the chilies I received were old, brittle, and dried out, I searched for another supplier of these often-hard-to-obtain peppers.
I was very pleasantly surprised to find my local spice shop (Oaktown Spice Shop) had them in stock. I grabbed a bag and was very happy with the quality of the peppers. They were supple, fragrant, and of a good size. And here's the bonus: the price was lower than I've found anywhere, $14.25 for two ounces. Every place I've checked online was about $11.00 or more for an ounce or so. I got excellent quality, supported a local business, got a great price, and saved quite a bit on shipping.
