Purchase a selection of a dozen baby food jars. Include meat, vegetable, fruit and mixed varieties for extra fun. Cover the labels on the jars with a piece of opaque paper and write numbers on the jars. When you're ready to begin the game, give each guest a sheet of paper and a pencil, then open the jars. Guests will examine each jar of food including smelling the food, or even tasting if they like. Then they are to guess the variety of the food. The guest with the most correct guesses, wins.
