Wrap slices of raw bacon around whole water chestnuts and secure with a toothpick. Place in a baking pan so they are not touching. Bake at 350 degrees for an hour. Drain. Now mix 1/2 cup catsup and 1/2 cup brown sugar together and pour over the wrap-a-rounds. Bake 30 minutes more. Good hot or cold. Make plenty, they won't last long.
