Asado AKA chili colorado also known as guiso de puerco depending on where you're from. Instead of just using ancho chilis, I use a combination of chili ancho, pasilla, guajillo, New Mexico, morita, arbol, and chili tepins. That sauce/gravy is worth the effort. I used to make up batches of it and freeze, then take to the ranch. Kill a pig and make up a batch right there with either the loins, shoulder, or a mixture of both. It's delicious.
I used New Mexico and Guajillo on this batch. I got 5 different recipes to try.
Cubed up the pork shoulder, dusted it in flour then fried in lard.
Sauce was below
7 New Mexico Red chiles
7 Guajillo
10 cloves of garlic
all blended together with about 6 cups of chicken stock
once I added it to the meat I added
Oregano
Cumin
Bay leaves
Turned out really good for my first try, it could use a little more heat.
Those are both great chilis, great flavor.
I cube up my meat and season with Fiesta brand fajita seasoning (try pork tenderloin - whole nother level) I coat my pot with just a little oil and brown the meat. Reduce heat and drop in 1 stick of unsalted Falfurrias Sweet Cream Butter and one chopped yellow onion. Caramelize until very dark. (I don't always do the onion)
For the sauce I stem and seed all of my chilis first, then bring a pot of water to a boil. Drop in 1 quartered red onion and one whole head of fresh peeled garlic, boil 5 minutes then drop all my chilis in and boil for 5 minutes. Remove from heat and let steep for 30-45 minutes. Then I drop all of that into a blender and add 1 TS salt, 1 TS black pepper, 1 TS Cumin, 1 TS smoked sweet paprika. I add just enough of the water from pot to cover, then blend all that up. Then I run it through a fine mesh strainer. Put the meat back in the pot, add sauce, and just enough chicken broth until the meat is barely covered. Then I simmer that for 2-3 hrs until the meat is fork tender and gravy is thick. Done.
