Common Toffee and Caramel Problems and Solutions (2)

It's happened to all of us—you're making a beautiful batch of caramel or toffee and all of a sudden you notice a thin, oily layer on top of your candy. Toffees and caramels both contain butter and sugar in high quantities. If the toffee or caramel is not handled properly during the cooking process, the butter sometimes separates from the sugar and forms an oily layer on top of the candy. This often happens during the cooking stage, but sometimes it separates as it is being poured out onto a baking sheet to cool.

Common Causes

One of the most common triggers is when the candy has undergone an abrupt temperature shift, either becoming too cold or too hot in a very short period of time. Monitor the temperature with a candy thermometer, and try not to "shock" your candy by drastically turning the heat up or down during cooking or even moving it around on the burner too much.

It is especially important to watch the candy at the beginning of the cooking process while the butter and sugar are melting together. If the two elements melt unevenly it can result in separation. If you have good stovetop burners,we recommend turning them to medium-low to allow the butter and sugar to melt gently in the beginning stages. If the heat is too high, but butter might melt too quickly and can separate from the sugar.

Toffee and caramel can also separate if the recipe calls for constant stirring and the candy isn’t stirred often enough. Take a recipe seriously when it tells you to stir constantly—give your arm a workout and never stop stirring until the specified moment.

Additionally, separation is more likely to occur when using thinner (cheaper) saucepans, as they don’t conduct heat efficiently and lead to “hot spots” that can cause uneven heat and allowing the butter to separate. Finally, humidity can cause the butter to separate, so if your kitchen is very warm and humid, it’s not a good time to be making candy.

How to Fix It

If your candy separates during the cooking process there is a chance you can save it. 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. Start with one tablespoon and stir the candy to help it come together. Add additional spoonfuls if necessary, but do not add more than 1/4 cup of hot water total.

If you have already poured your candy out to cool by the time it separates, the candy is unfortunately too far gone to save. However, once it solidifies, you can try wiping off the excess oil and crush the toffee to use to top baked goods or ice cream.

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.

Why is my toffee chewy and not crunchy? ›

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.

What to do if your toffee won't harden? ›

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.

Why does my toffee keep separating? ›

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.

Why add baking soda to toffee? ›

This toffee is cooked initially to 310°F (154°C), then the salt and baking soda are added, creating carbon dioxide. The foaming and bubbling aerate the candy somewhat, making the texture lighter and the candy easier to bite into.

What does overcooked toffee look like? ›

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!

Do you stir toffee constantly? ›

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.

Why is my toffee not set and why is it's texture grainy and not smooth? ›

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).

Is toffee overcooked caramel? ›

The difference between toffee and caramel is that caramel is made with white granulated sugar and cooked to 340 degrees Fahrenheit, whereas toffee is made with butter and brown sugar and cooked to 295 - 309 degrees Fahrenheit.

Why do you add vinegar to toffee? ›

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

What is the hard crack stage of toffee? ›

Finally, if the candy forms hard, brittle strands that easily break, the candy is at the hard crack stage, between 300°—310°F. Butter toffee and peanut brittle are examples of candies cooked to this temperature.

Why add water to toffee? ›

Adding the hot water lowers the temperature of the toffee mixture; therefore, continue to stir and cook the toffee until it reaches the correct temperature. 2. Burning Toffee: The color of butter toffee should be a rich golden amber color.

What does cream of tartar do in toffee? ›

Cream of tartar is a white powder sold in the baking aisle that's commonly used to stabilize whipped egg whites in meringues and cakes, prevent sugar crystallization in candies and caramel, and act as the activating ingredient in baking powder.

What is the difference between toffee and English toffee? ›

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.

How do I know when my toffee is ready? ›

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℃.

Why did a toffee fail to set despite using the correct ingredients? ›

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! Have patience and don't crank up the heat.

Why did my toffee turn out grainy? ›

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).

How do you keep toffee from crystallizing? ›

To avoid starting again, try these tips. Dissolve the sugar completely before increasing the heat and bringing the mixture to the boil. You'll know when it's dissolved - there won't be any crystals on your spoon. Brush any sugar crystals from the side of the pan with a wet pastry brush during the toffee-making process.

Should toffee be hard or soft? ›

Toffee is cooked longer to a much higher temperature – all the way to the 'hard crack' stage. This means that toffee will harden completely as it cools, and can then be cut or broken into pieces, to be added to other delicious desserts, or simply enjoyed by itself!
