Regarding the request for a sauce for sausage or party meatballs, the grape jelly and chili sauce is very good but the following is one that my friends and I always use for wedding receptions. Some guests say it's the best they've had.

Sausage or Party Meatballs

1 tablespoon butter
2 cloves sliced garlic (optional)
1 and 1/2 cups pineapple juice
1 and 1/2 cups brown sugar
1/2 cup ketchup
2 tablespoon vinegar
2 tablespoons cornstarch
Mix all ingredients in saucepan and stir over medium heat until well blended. Add meat balls (or sausages) and serve in a chafing dish.
This freezes beautifully.
