- 4 cloves garlic, skins left on
- 1 tablespoon olive oil
- 1/2 teaspoon kosher salt
- 8 tablespoons (1 stick) unsalted butter, at room temperature
- Preheat oven to 350° F. Place the garlic on a small sheet of foil and pull up the foil's edges to form a pouch. Pour the oil over the garlic and sprinkle with about 1/4 teaspoon of the salt. Roast for 35 minutes. Allow to cool slightly.
- Place the butter in a small bowl. Squeeze the garlic out of its skins onto the butter. Add the remaining salt and mash with a wooden spoon to combine. Chill the butter until needed, but allow it to come to room temperature before spreading.
