Step 1

Melt the butter with the garlic cloves over low heat. Let the mixture bubble gently until the garlic cloves become tender, about 10 minutes. Take care not to "toast" the butter or garlic cloves, removing from heat as needed to prevent browning.

Step 2

Whisk together all remaining ingredients in a saucepan and bring to a boil over medium high heat. Boil for 2 minutes, whisking constantly. Remove from the heat and allow to cool for 5 minutes before blending until smooth with a stick blender or a regular blender. Transfer to a jar to refrigerate. It may separate as it cools, so whisk it together before using.
