I've found that a crock pot is the perfect vehicle for creating the perfect onion confit. Don't use fresh, sweet onions for this, due to the lengthy cooking time. Please realize that this recipe is only a basic framework; your mileage may vary, so adjust accordingly! Length of crock pot cooking time is roughly 18 hours. Don't take them out until they are very dark and reduced, almost gelatinous in texture. Onion confit is fantastic on pizzas, as a sandwich spread, as an appetizer with thinly-sliced baguettes, etc. It makes a killer, quickie-base for French onion soup, too.
