1/4 cup water
1 cups sugar
To make the toffee, in a heavy based pot over a low heat, simmer the sugar, vinegar and water. Do not stir and keep it to the lowest heat possible. It will take 10- 15 minutes to start to caramelize and turn a golden brown, keep a careful eye on it or it will burn quickly.
Put the sticks in the apples and dip in the toffee and leave to cool and set.
And some pics from the next time we made them in April 2017. This time we bought the apples from the Hansens apple shed in White Beach, gorgeous little Lady in the snow apples. I only made half the toffee recipe and it made 12 little toffee apples.
