Place all of the ingredients in a sauce pan. Use an immersion blender to blend the ingredients.
Turn on the flame to medium-high. Cook the sauce until it boils. Reduce flame and simmer until it thickens.
Use in enchilada recipes as called for. Store any unused portion in the refrigerator for 4 - 5 days or freeze for future use.
Notes
If you don't have an immersion blender, place all of the ingredients in a blender. Blend until smooth. Then place in the sauce pan and follow the directions to create your homemade enchilada sauce.
