Sloppy Joe's (BBQ mix) to Serve 100

This is a recipe I found this on Page 14 of our farmer-oriented AGRI-VIEW  paper on May 13, 1988, and I made this up for the high school graduation parties we had for our children.  Other times, I've made this up and had it frozen in family-sized portions for when we'd get so busy with seasonal work around here.  Since then, I've had a number of requests for it.

BARBEQUE (100 servings)

18 pounds GROUND BEEF (CHUCK)

2 tablespoons SALT

1 of No. 10 can (the biggie!) of CATSUP

1/2 cup CIDER VINEGAR

1 teaspoon ground BLACK PEPPER

1/4 cup WORCESTERSHIRE SAUCE

4 cups (1 quart) finely chopped CELERY

2 cups finely chopped ONIONS

1 cup prepared MUSTARD

1 cup BROWN SUGAR

~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Brown GROUND BEEF (this works great in a Nesco type roaster)-- drain fat.  Add all other ingredients, mix well, and continue heating on low heat for 1 to 1-1/2 hours, checking and stirring occasionally to make sure nothing is sticking on bottom or sides of roaster.
