- 2 1/3 cups golden caster sugar (or very fine granulated sugar)
- 1/2 cup warm water
- 2 tablespoons liquid glucose
- 1 teaspoon white vinegar
- 8 apples (small, red)
- Boiling water
- 1/2 teaspoon red food colouring
1) Place the sugar, warm water, glucose, and vinegar in a large saucepan. Gently heat, while stirring, to dissolve the sugar, but make sure not to bring to a boil at this stage.
2) Once all the sugar has dissolved, raise the heat and bring the toffee to a rolling boil. Using a candy thermometer, boil to 270 F/140 C. This can take 10 to 20 minutes. If you do not have a candy thermometer, take a cup of cold water and once the toffee has started to thicken, drop a little of the toffee into the cold water. The toffee should solidify as it hits the water, and when you remove it from the water, the toffee threads should still be slightly flexible, not brittle. If the toffee is soft, continue to cook.
3) While the toffee is boiling, place the apples in a large bowl and cover with boiling water. Leave for a few minutes, then remove from the water and rub the apples with a tea towel and dry thoroughly. (The hot water and the rubbing will remove any waxy surface from the apple.) Once dried, remove the apple stems and push a chopstick or lollipop stick into the hole.
4) Line a baking sheet with parchment paper.
5) Once the toffee is ready, remove from the heat and leave to stand for 5 minutes to let the bubbles subside. (It is important to wait until all the bubbling calms down to create a smooth surface on the apples.) Once the bubbles have stopped, add the food colouring and stir gently.
6) Working quickly, tilt the pan slightly and dip the apples into the toffee; twirl around to completely coat the apple. Lift the apple from the pan and allow any excess toffee to drain away. Stand the toffee apple onto the lined baking sheet and leave to set around 20 minutes, or longer if possible.
7) If the toffee starts to thicken and harden as you are coating the apples, place the pot back on the heat and warm through, but do not boil. If you are not eating the toffee apples right away, wrap in cellophane.
8) Serve and enjoy!
