Heat the butter or oil in a medium saucepan over medium heat.
Stir in the flour and cook for 1–2 minutes, whisking constantly.
Slowly whisk in the hot broth, increasing the heat slightly as you whisk.
Once fully incorporated, add the tomato paste and stir well.
Reduce heat to medium-low, then mix in the spices.
Simmer for 3–4 minutes, adjusting chili powder to taste.
Use immediately over enchiladas or store in an airtight container for later.
Notes
Spice Level: Mild.
Storage Tip: This sauce keeps well in the fridge for up to a week. You can also freeze it in an airtight container for up to 3 months.
Sprouted Spelt Flour: Considered easier to digest than regular wheat (though still not safe for strict gluten-free diets). You can substitute a gluten-free flour, cornstarch, arrowroot, or really any other flour you'd like.
