This is not a recipe, it is more like an opinion.
Toasted garlic is terrific. Like savory candy.
I use 1/4 cup of olive oil and add 6 large cloves of garlic, minced. I use my smallest, cheapest saute pan and bring the oil to a very slow simmer over a very low heat. I cook the garlic for about ten minutes, shaking the pan every so often to redistribute. When it starts to turn light brown it's done. I like to let it sit off the heat for as long as possible before using it to let the olive oil get all toasty as well. And whatever you do, don't overcook it or it will be bitter.
I use it the oil and garlic together to dress pasta and salad and I add it to pizza sauce.
