The cranberry-onion relish is a hybrid of two classic Yankee turkey accompaniments: cranberry sauce and creamed pearl onions.
Bring a pot of water to a boil. Cook onions 2 minutes, then transfer to a bowl of ice water. Drain. Peel onions, and cut in half. Combine all ingredients in a saucepan. Cover, and cook over medium-low heat until cranberries burst and onions are tender, about 40 minutes.
