Popcorn Balls

1 cube margarine
1 cup sugar
1 Tbl. water
1 tsp. salt
2 tsp. vinegar
1/2 cup corn syrup

Melt all together in medium-size saucepan over medium-heat the whole time.  Use candy thermometer.  Cook to barely-above 100 degrees C.  (Don't let it reach 220 degrees F.)

Remove from heat and stir in desired food coloring.
Pour over 5 level quarts of popped corn. Stir to coat completely.  
Wait a minute or so before forming into balls, as hot candy will not set up as well.  Use wet hands to form into balls and put in plastic bags.
