Place the garlic on a piece of aluminum foil, drizzle with a little olive oil, and sprinkle with some kosher salt. Secure the top of the foil to make a packet around the garlic. Place the packet in a 350 degree oven (I love the toaster oven for this), and bake for about 30 minutes until garlic is soft and golden. Remove from oven, and allow to cool.
In the bowl of a food processor, combine roasted garlic, scraping oil and salt into the food processor as well, along with the remaining ingredients. Pulse until all ingredients are chopped and well combined.
Let the butter stand, covered, in a cool place for 1 hour to allow the flavors to develop. Store in an airtight container in the refrigerator.
