I like to make a huge batch of roasted garlic and freeze them into 2 tablespoon blocks.  I buy a large container of peeled fresh garlic at Costco and scatter them on a cookie tray.  Drizzle them with olive oil and a little salt and put foil over them and roast at 375 degrees for 30-40 minutes or until they are golden brown.  Take the foil off and allow them to get more golden if they are slow to brown. Put them in the food processor and whiz them down with a little olive oil or mash them and place them on a waxed paper lined sheet pan, drop large tablespoons on the paper and freeze them until frozen. Put them in a plastic container and keep them in the freezer until needed.  They are great for adding to mashed potatoes, sautéing with veggies, adding to stocks and soups, spreading on bread or crackers and the list goes on!
