3 tablespoons vegetable oil
1 cup ketchup
1 teaspoon Worcestershire sauce
1 teaspoon mustard vinegar
1 teaspoon white vinegar
2 tablespoons white sugar

Heat oil in a large saucepan over medium-high heat. When pan appears brown on one side, coat pan with a drop of olive oil. Place popcorn in the center of the pan and spread rolls slightly on top.
In a small bowl, mix grape juice, Worcestershire sauce, mustard vinegar, vinegar, sugar, vinegar, potato starch and salt. Mix well and pour over popcorn. Cover and chill in refrigerator.
When rolls of dough are cool, roll them into rings. Serve in bowls or in layers.
