Finding the chiles for this recipe was a little difficult for me. You might be able to find them at a Mexican grocery store if you go looking! They will be dried and most likely in the spice section.  If you don’t have time to drive 45 minutes one-way to a Mexican grocery store (darn suburbs-living), you can also order them offline! I ordered this package and it had everything I needed. And make sure to keep them on hand in case you want to make a Mexican mole in the future!
