Insert skewers in all the apples top center and set aside.
In a medium pan combine the sugar, water, corn syrup and food colouring. Stir over medium heat until the sugar has dissolved. Wash the sides of the pot down with a pastry brush dipped into clean water to prevent crystals from forming.
Turn the heat up and boil until mixture reaches the hard crack stage (150°c/310°F).
Dip the apples into the hot candy mixture and place on the baking paper to set and cool for approximately an hour before serving.
