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.

You can stir the mixture while the sugar is dissolving – but once it has started to boil, stop stirring. Instead, tilt and swirl the pan. Make sure your tin is prepared and sitting on a board or damp cloth before you start. Once you pour the hot toffee into the tin, it will heat up quickly.

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 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.

Taste is obvious: sweets made with dark brown sugar will have a slightly deeper flavor with those notes of caramel and toffee I mentioned.

This should NOT be a non-stick pan, because non-stick pans allow crystals to be pulled into the cooking toffee and will cause the batch to crystallize. The heavy pan distributes heavy evenly so the toffee cooks without burning.

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.

Butter is added in the final stages to add flavor and smoothness and inhibit large crystal formation. Use unsalted butter so you can add a small amount of salt (¼ teaspoon per stick of butter) to the sugar/liquid mixture.

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.

What temperature should toffee be cooked at? ›

Make sure that the point of the candy thermometer is not touching the bottom of your pan. Continue to stir occasionally, the mixture will slowly thicken and will turn a more yellow hue as it cooks, and cook to hard crack (305°F/151°C).

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).

If the sauce has separated then warming it gently and stirring occasionally should help it to come back together. If it still has a film of fat on the surface after warming then whisking in a tablespoon of hot water (from a freshly boiled kettle) can also help.

Pour the toffee onto the prepared baking sheet pan, allowing it to spread. Let cool for about 20 minutes. Use a mallet, rolling pin, or heavy object to crack the batch of toffee into small bits.

For maximum taste and texture, we do recommend that you either enjoy your toffee immediately, or store it in a refrigerator or freezer.

According to Blakeslee, if a candy appears extremely sticky or has a grainy texture, then it has most likely expired due to temperature abuse and the crystallization of sugar. As a result, she said, it may develop an off flavor, have a change in color or turn moldy if it contains fruits or nuts.

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.

It can also be caused by the mixture being heated unevenly (if the pan has a thin base and has hot spots). We would suggest using a heavy-based pan and heating the mixture slowly, stirring occasionally, until the sugar has completely dissolved, then letting it come gradually to a boil.
