Orange Popcorn Balls

1 1/2 cups granulated sugar
1 1/4 cups water
1 cup orange marmalade
1/2 teaspoon salt
1/2 cup light corn syrup
1 teaspoon vinegar
5 quarts popcorn

Combine sugar, water, marmalade, salt, corn syrup and vinegar in saucepan; bring to a boil, stirring until sugar dissolves. Cook to hard-ball stage or to 250 degrees F on candy thermometer. Pour over popcorn slowly; mix thoroughly.

Shape into 2 1/2-inch balls with buttered hands.

Black popcorn balls may be made by substituting one 6-ounce package licorice sticks, cut into small pieces, for orange marmalade.

Yields 15 balls.
