Place all ingredients in a blender and process until smooth.
Adjust the amount of buttermilk to get desired consistency.
*NOTE: If you do not have buttermilk you can easily substitute it with soured milk. Place 1/2 Tablespoon lemon juice or white vinegar into a 1/2 cup measuring cup. Top with milk and let sit 5 minutes. Use to replace buttermilk in any recipe!
