Oh the sweet perfume of garlic roasting in olive oil, just taking the scent in is like an appetizer. Years ago I had a restaurant where we served pizza and the roasted garlic was a very popular topping, we also made focaccia bread with roasted garlic. Each week we would roast several gallons of garlic for all the different uses.
Using it in mashed potatoes and in demi glace for braising chicken was popular at another place. Roasted garlic Caesar salad dressing, pasta dishes , spread for fresh bread or to toss with broccoli, brussels sprouts and various other vegetables.
Roasting the garlic not only makes it sweeter, more fragrant and creamy but also takes the bite out of it making it milder for people who prefer it less pungent.
