In large heavy pot, combine sugar, syrup and vinegar. Cook over medium heat until sugar is dissolved, about 7 minutes. Then cook, stirring constantly, 20 to 25 minutes or until mixture reaches 300-degrees when tested with a candy thermometer. Remove from heat.

Quickly stir in baking soda and mix well. Pour into buttered 12-by-15-inch pan. Do not spread. Mixture will spread itself. Cool completely then break into chunks.

Recipe makes about 1 pound Angel Candy.
