Add all ingredients to a blender and blend until smooth. Or place all ingredients in a large bowl and use a hand blender to blend until smooth.
Notes
Note, this recipe calls for dried chipotle pepper, not chipotle in adobo sauce. You can buy dried chipotle peppers here. Concerned about the spiciness? Pull back on the chipotle pepper by half. The smokiness will be much less, but so will the heat.
