This was Senator Joe Montoya's recipe, and the one I have more or less used as my base recipe for years.
2 pounds boneless pork, cut into 1" cubes.
3 tablespoons all-purpose flour.
2 tablespoons butter, lard or bacon drippings
1 cup chopped onion
2 or 3 garlic cloves, minced (more if you like, I do.)
3 cups of chopped peeled tomatoes
1 teaspoon salt
1/2 teaspoon ground Mexican Oregano
1/4 teaspoon ground cumin
20 green chiles peeled and chopped.
Lightly coat pork cubes with flour. Melt butter in a large heavy pot. Add pork cubes a few at a time stirring to brown well. Add onion and garlic, cook until onion is soft. Stir in the browned meat and cover with water.
Add tomatoes, salt, oregano, and cumin. Cover and simmer about 1 hour, stirring occasionally and adding water as needed.
NOW add the green chiles and simmer another 30 minutes or more adding water as needed.
I use chicken or beef stock instead of water most times and of course don't add salt. Sometimes I cube some potatoes and add at the same time as the green chiles. A good old beef pot roast makes a nice change from the pork too. And most important!!!!! It is Chile not Chili, you're goint to have everyone thinking your one of them yankee varmints!
