Add all ingredients into a blender. Bring the blender to high speed until smooth.
If you have a high-speed blender, like a Vitamix, just keep the blender running on high until the sauce gets steamy and thick, about 5 minutes. If using a regular blender, pour blended mixture into a saucepan, bring to a boil, and simmer until thick.
This sauce works fabulously in mac and cheeze, and can be made without adobo if you don’t want a Mexican queso sauce.
