Manwich Sauce

This is a recipe from Jackie Clay at Backwoods Home.

Manwich Sauce (Sloppy Joes)

1 gallon peeled, cored, chopped ripe tomatoes
2 cups chopped celery
2 cups chopped onions
1 1/2 cups chopped sweet bell peppers
1 cup brown sugar
1/2 cup corn syrup
1 clove garlic, minced
1 Tbsp paprika
1 Tbsp salt
1/2 cup vinegar

Combine tomatoes and vegetables in a large kettle and cook down for about 30 minutes. Press through a food mill. Cook down until it is reduced to about half in volume. Add remaining ingredients and cook slowly until mixture is the consistency you want (about an hour). Stir more and more frequently as it thickens or it will scorch. Pour hot into hot jars. Process pints 20 minutes in a boiling water bath, quarts 35 minutes
