How to Melt Sugar

Melting sugar breaks the bonds of granulated sugar so it can be recrystallized into different shapes by using molds or other tools. Melting sugar is also the first step in making caramels and candies. The melting temperature determines what can be made with the sugar.^{[1]

Research source} The process isn't difficult, but it's important to monitor the sugar carefully so it doesn't burn. See Step 1 to find out how to start.

How do you melt sugar?

Measure out the amount of sugar you want to melt.
Place the sugar in a pot with half the amount of cold water.
Heat over medium low heat.
Stir the mixture continuously with a wooden spoon.
Remove the sugar from heat once it’s melted.
If you want to make caramel, keep cooking without stirring for 8-10 more minutes.

2 tablespoons water

Measure out the sugar. Determine how much sugar you want to melt. Since sugar is so tricky to melt evenly without letting it burn, you shouldn't attempt to melt more than 2 cups at a time.^{[2]
X
Research source} If you need more for your recipe, melt a second batch separately.
- Use white granular sugar, also known as table sugar.
- A good rule of thumb when melting sugar is that 2 cups of sugar will make enough melted sugar to make 1 cup of caramel.
2
Place the sugar and cold water in a heavy-bottomed pot. A heavy-bottomed pot insures an even distribution of heat. A medium-sized saucepan is usually perfect to use for melting sugar. Aluminum or steel pots work best.
- Use half as much cold water by weight as the amount of sugar you are using.
- Make sure the pot is completely clean. If sediment is left in the pot, sugar crystals could form around it.
- A pot is a good option—it has a lot of surface area that will be hitting the sugar.

Research source} Using low heat means the sugar will take awhile to melt, but don't be tempted to turn it up; sugar will quickly burn when cooked over higher heat. Using low heat gives you better control.

Stir continuously until the sugar is dissolved. Stirring at the beginning of the process helps break up lumps and make sure that the sugar is heated evenly. It's best to use a wooden spoon. Keep stirring until the sugar mixture turns clear and begins to boil. At this step, different candies can be made based on the final temperature of the sugar.
- Use a pastry brush to wash any sugar off the edge of the pan back down in with the rest of the sugar.
- If crystals form on the edge of the pan, they can seed crystal formation in the entire mixture and the sugar will seize. Brushing the sides of the pot very carefully with warm water can prevent this.

Cook for 8 to 10 more minutes without stirring. Once the sugar has melted and starts to boil, let it cook until it caramelizes.^{[4]

Research source}
- Stirring at this point could cause crystal formation, so don't stir any more from this point on.
- The pan may be gently swirled to even the cooking process.
- The resulting caramel color should be a slight golden brown that forms at the edge of the pan.
2
Check the temperature of the sugar with a candy thermometer.
- If you want the sugar to stay in its liquid form, it is ready when it reaches 340 to 350 °F (171 to 177 °C). At this point the color will be a rich golden brown.
- Removing a small spoonful of the mixture and placing it on a white plate will show the caramel's true color.

Look for the appropriate doneness. Different temperatures are desirable for different applications. When your sugar reaches the desired temperature for your particular recipe, it is done. Use it immediately.
- Thread stage: 223 to 233 °F (106 to 112 °C) A teaspoonful of sugar will form thin threads when dipped into and removed from cold water. It is good for candying fruits and nuts.^{[8]

Question

At what temperature do you cook sugar and water so that it turns white when cooled?

Community Answer

None. It either cools to a clear color (ranging from glass to dark amber) or you start folding the caramel while it is hot. This is hard to do without special equipment like cooling tables and hooks.

Question

Why is my caramel too hard?

Community Answer

It could be that you cooked it too long then let it sit, or that there's not enough butter.

Tips

If you do not have a pastry brush, you can put the lid on the pot. The steam created will help wash down any sugar that may have gotten up on the edge of the pot. Make sure you leave the lid tilted to the side to let out some of the steam and be careful to monitor the sugar carefully. This method is not as certain to work as using a brush, so it is still possible that your sugar will seize.

Make sure all of your equipment is completely clean. Impurities on the pot can cause your sugar to seize because they can seed the growth of sugar crystals. Sugar seizing is when sugar crystals form and the sugar takes on a grainy texture. If your sugar seizes, the only thing to do is throw it out and start all over.

While high humidity can soften sugar sculptures and spun sugars, which are made with melted sugar, the melting process itself is not affected by humidity levels.
