Barbecued Hamburger Mix (aka Sloppy Joes)

4 medium onions, chopped
3 cloves garlic, finely chopped
2 cups chopped celery tops
4 pounds hamburger
1 tablespoon salt (go a little light)
1/2 teaspoon pepper
3 tablespoons Worcestershire sauce
2 12-ounce bottles catsup (~2 1/4 cups)

Pan-fry onion, garlic, celery and hamburger in a dutch oven or large skillet. Stir and cook until all redness of the meat disappears. Add salt, pepper, Worchestershire sauce and catsup. Simmer 20 minutes and skim off excess fat. Use part or all immediately or cool quickly and freeze for later use. Makes 10 cups–5 1-pint containers. One pint makes four sloppy joes.
