Everton Toffee
Ingredients
Directions
Make the toffee
Put the butter into a large saucepan and melt it.
Add the sugar and treacle once the butter has dissolved.
Stir gently with a knife and boil for about 10 minutes.
Drop a little off the knife into a basin of cold water; if it is crisp, it's done.
If not, boil a little longer.
Set and mark
Butter a tin, pour the mixture into it, and mark out into squares as it begins to set.

What each ingredient does
- Treacle
- Adds deep flavour and a chewy, sticky texture to the toffee.
- Moist sugar
- Sweetens the toffee and, once boiled, helps it set firm and brittle.
- Butter
- Adds richness and a smooth texture, and helps keep the mixture from sticking.
The step that matters
Testing for doneness in cold water. Toffee sets by reaching a high sugar concentration as water boils off. Stopping too early leaves it soft and sticky; boiling too long makes it hard and bitter. The cold-water drop test shows when it has reached the crisp stage.
