First of all, melt the butter.
2 tablespoon butter
Add the flour to the butter, stirring constantly and make sure not to get burned. Cook for about 1 minute.
2 tablespoon flour
In the pan add the chili, cumin, salt, garlic, oregano and pepper. Add the tomato sauce and stir until everything is well combined.
2-3 tablespoon chili powder, 1 teaspoon garlic powder, 1 pinch oregano, 1 pinch black pepper, 1 pinch ground cumin, 1 pinch salt, 6 oz tomato sauce
Pour the broth slowly into the mixture while stirring, followed by the vinegar.
3 teaspoon apple cider vinegar, 2 ½ cups broth
Leave the mixture to simmer for 10-15 minutes until it becomes thick.
Remove from heat and place the sauce in a jar and store it in a fridge for a few weeks.
If you want the sauce to be usable for longer by canning your enchilada sauce, put the jar in a pot filled ¾ with boiling water and leave it to simmer for around 20 minutes to seal.
