Place the peeled shallot and garlic cloves on a piece of foil and close tight. Roast for thirty minutes or until soft to the touch. Let cool.
Place all of the ingredients in a small blender or food processor and blend until the shallot, garlic, and rosemary is broken down and the mixture is creamy. It won’t be thick, just creamier than the typical vinaigrette salad dressing.
