This one sounds simple. I found it through Google. Some had worcestershire sauce, orange juice and other ingredients, but this one sounds simple and what a raisin sauce normally would be. This was served on ham:

1/2 c. brown sugar, packed
1 tsp. dry mustard
1 tbsp. cornstarch
1 1/2 c. water
1/4 c. vinegar
1/2 c. raisins
1 tbsp. butter

Raisin Sauce: Mix brown sugar, mustard, and cornstarch. Add water, vinegar, and raisins. Cook and stir until thick. Add butter; blend. Makes about 2 cups.

This is the one I always use. It is sooooo goooood!
Orange Raisin Sauce

1 ½ T cornstarch
1/8 tsp mild mustard
1/8 tsp ground cloves
¼ tsp ground allspice
¼ tsp ground cinnamon
½ c vinegar
1 c water
1 c orange juice
orange zest
1 c seedless raisins, soaked in hot water 1 hour
2 T butter

1. Combine sugar, cornstarch, mustard, cloves, allspice, cinnamon in saucepan. Mix in water, orange juice, zest and vinegar. Add drained raisins. Cook over low heat, stirring constantly, until sauce comes to a boil, and is thickened and smooth. Stir in butter. Serve over ham or pork

My dad always put crushed pineapple in his--along with the raisins, spices, brown sugar, etc. Couldn't give you a recipe you could use, though--he used to make it in multi-gallon pots for the ham dinner he ran for a service club he was in.

Thank you so much for the recipes. Those sound like exactly what I'm looking for. I want to spice up our Christmas ham and the New Year's pork loin. I knew the KT would come through for me! :)
