1. Prepare some rock sugar. You can use rock sugar or white sugar to fry the sugar color. In comparison, rock sugar is better, and the color of sugar fried with oil is better than that of water. 2. Put 100 grams of rock sugar and 20 ml of oil into a clean pot. Remember to put cold oil into the pot instead of hot oil. This will make it easier to operate.

3. After turning on medium heat, stir-fry the rock sugar continuously to let the sugar melt quickly. When you see the rock sugar melting, adjust the low heat immediately to avoid burning it due to high heat.

4. After lowering the heat, stir-fry continuously. During the stir-frying process, big bubbles will appear first, and then small bubbles will appear after continuing to stir-fry.

5. When small bubbles appear, the pot is already brown-red. At this time, immediately pour hot water and stir evenly with a spoon.

6. Then turn it to high heat, cook for a few seconds, and mix the water and sugar in the pot together.

7. Turn off the heat and let it cool down naturally. Put the sugar color into a well-sealed container, cover it, put it in the refrigerator, and use it directly when it is ready to use to add color to the ingredients.
