Warehouse clubs offer great bargains, but only if you can take advantage of the quantity.  This article highlights the preservation of peeled garlic.

You've seen the bag of garlic at Costco and Sam's Club.  It's fresh, it's peeled, and it comes in a whopping three pound bag.  Most of us can't use it fresh all at once, but if you prepare it in a food processor, add some salt and oil and freeze it, it will keep for six months or more and be more flavorful and useful than fresh.

First, wash the garlic in a colander.  Pat dry.  Then, place half of it in a large food processor and add a few tablespoons of oil and a teaspoon of salt.  Pulse to desired size.  Scoop the contents into a gallon Ziploc bag.  Repeat with the second half of of garlic.  Place in the same Ziploc.

Put the contents in the freezer and check on it in 3-4 hours.  Gently break up frozen chunks and place back in the freezer.  Repeat one more time.  The mixture will keep for at least six months.  Your frozen garlic can be used as you would use fresh garlic with the added benefit that it doesn't burn as easily when stir frying. Personally, I think the flavor is better than fresh because of the addition of salt and oil  and because the chopping action releases more intense flavor.
