Roasting garlic will give you a good mouth-filling taste of garlic but without the sharp pungency of fresh. You can substitute it in almost any recipe calling for garlic. Experiment and see if it is better.
It is worth planning an Italian night just to use up any leftover garlic you have. Spread some good Italian bread with butter then the room-temperature roasted garlic mash. Sprinkle with salt and bake in the oven until toasted for some of the best garlic bread you will ever eat.
