Using a sharp knife, cut off the top of each head of garlic so the cloves are exposed.

Drizzle 2 teaspoons of olive oil over each garlic head, then wrap the garlic in foil.

Roast for 35-40 minutes or until the garlic cloves are tender.

Remove the roasted garlic from the oven and let cool. When cool, use a spoon to remove the roasted garlic cloves and crush them in a small bowl.

In a medium saucepan, combine all the ingredients. Stir well.

Bring to a boil, then reduce to a simmer. Simmer for 20 minutes, stirring often.

Adjust salt and black pepper to taste.
