First roast the garlic. Preheat the oven to 180°C. Peel any excess skin off the garlic bulb, but leave it together. Chop the very top off the cloves to they are slightly exposed. Drizzle on a little olive oil, season with salt and pepper and wrap the whole bulb in tin foil. Bake in the oven for 30 minutes then leave to cool. Use a knife to remove the inside of the cloves into a bowl, they should easily slide out of the skins and be very soft.
