A1 Steak Sauce

1/2 cup water
1/4 cup golden raisins
1/2 cup aged balsamic vinegar
1/4 cup Worcestershire sauce
1/4 cup ketchup
1/4 cup dijon mustard
1 pinch cayenne pepper
1/4 teaspoon black pepper
2 garlic cloves, cut in half
2 tablespoons onion, chopped
1/2 teaspoon celery seed
1/4 teaspoon kosher salt
1/2 orange, cut into 2 pieces

Add the ingredients (except for the orange juice) into a small saucepan.
Squeeze the oranges into the pan, then drop in the rinds.
On low heat, stirring occasionally, let it simmer for 15 minutes.
Careful to keep the heat low allowing for a very low gentle heat, not a hard boil.
To check doneness dip in a spoon and run your finger over the back, the line should stay clean.
Turn off the heat and strain out the garlic and orange pieces.
Let cool completely before serving.
