Common Toffee and Caramel Problems and Solutions (2024)

FAQs

How to fix caramel that crystallized? ›

Reheat low and slow: If your caramel sauce has seized up with the butter/cream additions or still has crystalized sugar at the end of making it, place it on the saucepan on low heat for a good 15-20 minutes. This usually clears up most of my issues and results in a melted, smooth sauce.

Why is my sugar not caramelizing? If you don't add enough water, the sugar molecules will crystallize and become unstable when you turn off the heat. To fix this, add extra warm water to your pan and redissolve the sugar until it caramelizes.

If caramels are too hard, you can try placing them back in a saucepan, adding a couple tablespoons of water and stirring until the thermometer reads 242°F. Pour back into a prepared buttered pan. If caramels are too soft, that means the temperature didn't get high enough.

Adding an acid like lemon juice is another way to prevent sucrose from crystallizing. The cream and butter also act as “interfering agents” as the milk proteins in both help to prevent crystal formation. Ingredients such as vanilla, flavorings, salt, and nuts (or baking soda for caramel corn) are all added at the end.

Moderate the heat so the toffee doesn't scorch and burn, and you only need to stir 3-4 times. When stirring, don't scrape the sides of the pot. That can also cause the toffee to crystallize and/or separate into a butter layer. Cook the toffee until it is a beautiful deep golden brown.

Caramel becomes grainy when the sugars crystallize, a process that happens when the melted sugar splashes up onto the cold sides of the pan. It loses its moisture and turns back into a sugar crystal. If this crystal touches the melted mass, it causes a chain reaction and the caramel will seize up and become grainy.

you simply haven't cooked it enough-- possibly your microwave is less powerful (the original recipe doesn't specify a wattage for cooking the caramel) or the butter you used has a higher water content. You could try cooking the mixture for a little longer, and seeing if it sets up firmer.

Like dry caramel, you want to gently move the sugar mixture in that same side-to-side paintbrush-like fashion until the sugar dissolves. Then, as soon as the mixture comes to a boil, it should not be stirred, as the agitation can cause crystallization.

Why didn't my toffee turn brown? It will turn brown if the heat is med-high and you cook it for 5-6 minutes. Crank up that heat, don't let it simmer on low. It will start out yellow, then become light brown, then finally the right brown paper brown that you are looking for.

Why is my homemade caramel not thickening? ›

Reduce the amount of milk.

If you know that you want a thick caramel sauce, cut down on the amount of milk that the recipe suggests. Leave out about 1/3 or 1/2 of the recommended milk. This will result in a caramel sauce that's thicker and that you won't have to spend extra time simmering.

Add acid. Acid ingredients (like vinegar or lemon juice) can help prevent re-crystallization which causes caramel to become grainy. Acid physically breaks the bonds between the glucose and fructose molecules that form sucrose and ensure that it stays apart.

Light Corn Syrup: This is an imperative ingredient that gives the caramel a softer, chewier consistency. Also, and more importantly, corn syrup helps prevent the cooking caramel from crystallizing into a gritty, grainy texture.

A caramel can split if there's fat in the caramel (e.g. from butter or cream). Often, a split caramel can be saved by gently reheating the caramel and stirring continuously. Adding some extra water can also help here to mix everything again before boiling off that extra water one more time.

The caramel may seize. If clumps of sugar form, continue heating on low heat until they melt back into a smooth sauce. Remove from heat and pour through a fine mesh strainer into a heatproof container. Stir in the salt (if using).

To thin caramel, just add some cream or water over heat. Melt caramel loaves in the oven. You can also add corn syrup or lemon juice to caramel sauces to prevent them from crystallizing.
