Place the apples in a large bowl and cover with boiling water (this will remove the waxy coating).
Using a slotted spoon carefully remove the apples from the water and dry.
Push a lollipop stick into the stalk end of each apple.
Heat the sugar and 100mls of water in a pan over a medium heat.
Cook for 5 minutes or until the sugar dissolves and then add the vinegar and the golden syrup.
To test that the toffee syrup is ready, pour a teaspoon of it into a glass of cold water and if it hardens instantly its ready.
Holding the lollipop stick, carefully dip each apple into the toffee syrup and coat evenly. Then place each apple on a lined baking tray.
Allow to set in the fridge and serve.
