Wash & dry apples, remove stems, and insert a stick into the center.
In a pot over medium heat, heat sugar, water and corn syrup until boiling.
Continue to boil for 10-15 minutes until the sugar mixture reaches 300 degrees.
Remove from heat, and stir in the food coloring and flavor oil.
Carefully (but quickly!) dip each apple, and place on a sheet of parchment paper to cool/set.
When the black candy is hardened, use red icing to pipe an hourglass shape on to the center of each apple.
