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. Cook until the toffee registers 285-290 degrees on an instant-read or candy thermometer and is deep amber brown in color, about 20-25 minutes.

Low and slow

Simmering the syrup for English toffee to the requisite 300°F temperature can (and should) be a slow process — up to 20 minutes or so. 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.

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

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). Once toffee reaches 305°F/151°C, immediately remove from heat and stir in vanilla extract (careful, it bubbles and steams a bit).

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.

You need a very sturdy pan which is KEY to even heat distribution. Thinner, cheaper pans can scorch the cooking candy and/or cook it unevenly. Here are some great choices: Anolon Nouvelle Copper and Cooks Standard. I own a couple pricier copper pots because of the amount of candy I make.

For cooking: cook the toffee until it turns nutty brown. Don't stop cooking it until it's brown. Stop cooking it immediately as soon as it's brown.

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).

You might wonder why the toffee recipe includes baking soda. It is added at the end of the boiling stage and creates lots and lots of bubbles. These bubbles help to lighten the texture of the finished toffee, resulting in an easier-to-bite candy.

Conservatively, our toffee will keep well in the refrigerator for three weeks (take care to guard against moisture getting to it), and three months in the freezer.

Is toffee just burnt 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.

Ideally toffee has a nice snap when you bite into it, but then it gives way to a tender texture that immedietly crumbles and dissolves in your mouth. Even though I add a tremendous amount of butter to my recipe, the texture I end up with is more like a hard candy that ultimately sticks to your teeth.

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.

Adding water to sugar before caramelizing it helps it melt at a more even rate, and helps reduce the risk of crystalization. You only need to add enough water to turn the sugar into a slurry, and it all boils off as you heat the syrup.

Toffee Making Tips + Troubleshooting

Your toffee is better off overcooked than undercooked! 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!

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.

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.

I find that vigourous stirring keeps the 20 lbs or so of toffee from separating, so that's a good tip. And I've always been told that stirring TOO vigorously can cause separation also.
