Meanwhile, heat oven to 400 degrees. Wrap individual garlic cloves in aluminum foil and set on a baking sheet. Roast for 15-30 minutes, or until soft.
Remove papery flesh of garlic cloves and mash "meat" in a separate bowl.
In the bowl of stand mixer fitted with the paddle attachment or a large mixing bowl with an electric mixer, blend together cream cheese, sour cream, fine sea salt, ground black pepper, mashed roasted garlic and cayenne. Beat until well mixed and creamy.
