Red enchilada sauce:
1 tbsp vegetable oil
1 minced onion
1/2 tsp salt
3 tbsp chili powder
3 garlic cloves (minced)
2 tsp cumin
2 tsp sugar
16 oz tomato sauce or passata
1/2 cup water
pepper
Heat the oil in a 12 inch skillet over med heat until it shimmers. Add onion and salt and cook until onion is soft, about 5 mins. Stir in chili powder, garlic, cumin, and sugar. Cook until fragrant, about 15 seconds. Stir in passata and water. Simmer and cook until slightly thickened, about 5 minutes. Season with salt and pepper to taste.
I'm going to work on adapting this with the tomatillos I'm growing this year because I miss my green sauce!
