Stopping Toffee from Crystalising? ›

Two steps you can take for preventing crystallization include brushing the walls of the pot with water as it cooks to wash down any sugar syrup, or covering the pot with a lid to trap the steam until all the sugar has dissolved.

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.

Keeping the lid ajar will allow some steam to escape as the sugar continues to cook. Add a little acid (such as a touch of lemon juice) or corn syrup to the sugar-water mixture before cooking; they help interfere with crystallization.

Add Moisture: If the sugar is melted but you still see a few crystals- sometimes adding some liquid like water or heavy cream to the mixture can help dissolve any sugar crystals that have formed and promote a smoother texture.

This method may still result in some crystallization after 48 hours. For the sugar-water ratio of 2:1 needed for rich syrup, add ¼ teaspoon of either corn syrup or a mild acid. Adding more of the syrup or acid will affect the flavor noticeably.

Crystallization may be prevented by adding an interferent, such as acid (lemon, vinegar, tartaric, etc.) or glucose or corn syrup, during the boiling procedure.

A diet lower in sodium and higher in potassium — contained in many fruits and vegetables — can reduce the risk of stone formation. Continue eating calcium-rich foods, but use caution with calcium supplements. Calcium in food can actually lower your risk of kidney stones.

Crystallization process can be controlled by two ways; either by controlling the crystallizer temperature or by controlling the crystallizer concentration. Inlet jacket temperature is used as the manipulated variable. As the jacket temperature is changed, concentration and temperature of the crystallizer is changed.

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. The easiest way to prevent crystallization is to avoid stirring the caramel. Instead, swirl the pan gently to help the sugar melt evenly.

If too many bits of sugar get stuck to the side of the pan, they will harden and can cause the caramel to seize or become gritty or grainy when you add in the butter and/or the cream. Prevent this by gently swirling the sugar around as it melts, while holding the pan's handle, instead of using a utensil to stir it.

How to save separated toffee? ›

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.

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).

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.

Corn syrup contains glucose, which has enough acid to prevent re-crystallization during the cooking process. It is an excellent addition to sugar when making cara- mel, brittle, and hard candies.

Cook the syrup on a burner larger than the diameter of the sauce pan. This will keep the sides of the pan hot and help prevent crystallization. Include ingredients that prevent crystallization, such as corn syrup and acids (e.g., lemon juice and cream of tartar).

It's important while the toffee cooks to only stir it occasionally. Constant stirring can cause the toffee to crystallize and separate. For those of you that need to know exactly how often you should stir, I would suggest erring on the side of not stirring more than stirring.
