In a heavy pan, combine sugar, water and syrup. Cook, stirring, until mixture boils. Put on the lid to melt down crystals (about 1 min).
Remove cover and cook on moderate heat to 300º (buy a candy thermometer). Add 1/4 to 1/2 tsp oil flavoring and color as desired. Continue to stir until completely blended.
Pour onto buttered baking sheet. When cool, cut or break into pieces. Store flavors separately for 24 hours, then they can be stored together. Keeps forever!
