Preheat oven to 400°F (200°C). Prepare the garlic: Cut off the top 1/4 inch of the garlic head, exposing the cloves. Drizzle with 1 tablespoon olive oil and sprinkle with a pinch of salt. Wrap in foil and roast for 30-35 minutes, or until cloves are very soft and golden brown. Let cool slightly, then squeeze out the roasted garlic pulp.
