Common Toffee and Caramel Problems and Solutions (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.

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.

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.

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!

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.

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).

A ball of toffee that feels soft and squeezable will be at 'soft crack' stage. A firmer ball that's harder to shape will be at 'hard crack' stage. Some recipes cook the sugar at a lower temperature in order to make softer toffee.

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

Why won't toffee set? ›

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.

300° F–310° F

The hard-crack stage is the highest temperature you are likely to see specified in a candy recipe. At these temperatures, there is almost no water left in the syrup. Drop a little of the molten syrup in cold water and it will form hard, brittle threads that break when bent.

Adding cream of tartar when you're making candy helps prevent the creation of sugar crystals. That's why lots of icing, syrup or candy recipes call for it: it makes it so the end product doesn't have large crunchy sugar capsules.

English toffee and American toffee diverged with the preferred use of sugar type. English toffee is made with brown sugar, while American-style toffee, known as buttercrunch is made with white table sugar (granulated sugar). Buttercrunch is typically dusted with crushed almonds or other nuts.

Using a candy thermometer is the most precise way to tell when your toffee is done. If you want to use a candy thermometer, you will want to cook the toffee until it reaches about 300℉/149℃.

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!

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).

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.

Toffee is a hard candy made by cooking a sugar syrup with butter to the hard crack stage, 300–310°F (149–154°C), and then pouring it out to cool. It can have inclusions or not, and it can be made either very dense and hard or can be lightened by adding baking soda when the candy is almost done cooking .
