Fresh Tomato Relish

It is that time of year again when tomatoes are in season. This is not a sweet relish like chili sauce. It is more like a salsa. Freeze a batch for next winter.
Fresh Tomato Relish
2 cups while vinegar
1/2 cup sugar
8 cups chopped peeled ripe tomatoes
1 cup chopped onion
1 diced medium green pepper
2 celery ribs, diced
1/2 cup prepared horseradish
2 tablespoons salt
1 tablespoon mustard seed
1-1/2 teaspoons black pepper
In a small saucepan over medium low heat, bring vinegar and sugar to a boil. Remove from heat and cool completely. Meanwhile, in large bowl combine remaining ingredients. Add vinegar mixture and mix well. Spoon into pint or half pint canning jars, leaving 1/2 inch headroom. Refrigerate up to 2 weeks or freeze up to 12 months. Makes 6 pints.
