Over in the events forum, Hammond mentioned that he received a gift of chiles de árbol from the Maxwell Street chile guy. That thread has devolved into a recipe discussion, but I’m putting my response over here in Shopping and Cooking where it belongs!
David Hammond wrote: Desperate for an early lunch, I reheated some of The Wife's potato soup, and was able to amp up the otherwise bland broth with some chiles, fried quickly in olive oil (those guys brown fast!) and crumbled into the soup after it was heated (to avoid spreading piquancy throughout). It really helped. Now, I'm getting ideas about using the chiles in eggs, potato salad, and other basically neutral foods. Very pleasant burn.
Chiles de árbol (usually toasted?) seem to be especially well suited as a condiment, added to taste to increase the heat level, as Hammond did with fried chiles in his lunch today. Antonius and I have had them this way in a couple places we’ve posted about, with the carne en su jugo at Taquería Tayahua, and with the birria at Reyes de Ocotlán. These chiles are also the basis for some of the bottled salsas, such as the one which tortas ahogadas are drenched in. I have a recipe for making that kind of salsa (start with 70 chiles de árbol), but really, is it worth the trouble when you can buy a good product in the stores?
We’ve enjoyed a nice salsa with tomatillos and chiles de árbol made by friends of ours from the state of Guanajuato; I’ve also had this at Mi Cafetal, which is run by a couple from Leon, Guanajuato. (The salsa is surely more widespread than just in Guanajuato, though.)
Patricia Quintana, in
The Taste of Mexico, has a simple recipe for such a salsa:
30 tiny tomatillos, husked and roasted
4 cloves garlic, roasted
2 cloves garlic, whole
Salt to taste
4-6 chiles de árbol, fried
¼ c white onion, chopped
I’ll paraphrase her instructions: the tomatillos get ground up in a molcajete with both types of garlic. Add salt. Add chiles and grind again. Put in enough water to make a sauce, adjust the salt, and finally stir in the onions.

Either in a salsa or toasted and crumbled over food, these chiles are a great way to increase the heat level for one or two diners when others at the table prefer blander food. A situation we know well in our own family, in fact.
