How To Make Homemade Toffee - Common Toffee Making Fails and Fixes (2024)

FAQs

What can go wrong when making toffee? ›

Stirring too quickly or too often can cause the toffee to separate. Moderate the heat as needed – turn it down if the toffee is boiling or cooking too fast so it doesn't burn.

Don't hurry this gradual transformation; syrup that doesn't reach 300°F, or close to it, will make candy with timid flavor and chewy (not crunchy) texture. Think you can save time by bringing the syrup to a full rolling, popping boil in order for it to darken more quickly? Think again.

If your toffee doesn't have a hard texture (where you can snap it in half) you did not cook it long enough. Again, the 5-minutes is just a guide. Cook it until it is the color of a brown bag.

This usually happens when the toffee mixture is heated too quickly or at too high of a temperature. Make sure to use medium heat (or medium-low) and go SLOW!

Once boiling, cook, stirring only 2 to 3 times, until it turns a dark amber color and the temperature reaches 285 degrees F (137 degrees C) on a candy thermometer, 20 to 30 minutes. Immediately pour toffee into the prepared baking dish.

If the toffee mixture has not boiled for long enough the toffees will not set. It is very important that you test toffee in a glass of cold water for it to crack or that the toffee has become hard on the spoon.

This recipe includes a dash of vinegar which will help keep the colour of the toffee clear and bright and banish any cloudiness.

Toffee Making Tips + Troubleshooting

Undercooked toffee won't be anything more than a caramel sauce. But overcooked toffee will be just slightly crunchier (almost unrecognizably). So, always err on the side of over-cooking!

To help prevent crystallisation, an acid/fructose such as lemon juice or cream of tartar can be added before boiling, or a glucose solution. This makes the molecules odd shapes and harder to form geometrical solid blocks. So it helps keep them separate, enabling a clear toffee.

Brittles and toffees accumulate small amounts of acid from the browning reactions that occur during cooking. This is one reason why the baking soda is added at the end of cooking. The soda reacts with the acid to make bubbles, and the syrup foams.

What is the difference between English toffee and regular toffee? ›

English Toffee is a nationwide favorite that is easily made with only a few ingredients. The difference between regular toffee and English Toffee is one important ingredient – butter! I make English Toffee throughout the year for special occasions and it's always a big hit.

Sometimes separated toffee or caramel can be saved by removing the saucepan from the heat and stirring constantly until it comes back together into a smooth mixture. Gradually return it to the heat, stirring constantly. You can also try adding a spoonful or two of very hot water to the toffee to help it come together.

As the toffee cools and the molten sugar crystals become solid again, they are attracted to the 'seed' forming new lumps of tiny crystals – hence the grainy texture. This can also happen if the toffee is stirred, or agitated, after it has begun to boil or on cooling (as happened with this pink-tinted toffee).

The butter, sugar and syrup are melted together and should form a smooth sauce. When the sauce cools it should remain amalgamated. If the butterfat separates out then usually this is due to the mixture being either heated or cooled too quickly, which "shocks" the mixture and causes the fat to separate out.
