There are two reasons. One is that the amount of sugar may not be enough; the other is that the sesame candy is made or the ingredients are wrong. The specific method is as follows:

Ingredients: black sesame\t800g, maltose\t400g, white sugar\t400g, water\t200g

1. First, put the sesame seeds into the drain. In a basket, drain out the water and drain.

2. Then pour the sesame seeds into the wok and stir-fry over medium-low heat.

3. During the stir-frying process, the moist sesame seeds will emit heat and the sesame seeds will slowly dry out.

4. Then stir-fry the sesame seeds until they are no longer steaming, and twist the sesame seeds with your hands to break them up. When they become fragrant, take them out and set aside.

5. Put all the sugar, maltose and water in the pot and bring to a boil over medium heat.

6. After boiling, you can see bubbles, then turn to medium to low heat and cook, stirring constantly.

7. When the color starts to slowly turn yellow (the color in the picture below), you can start to taste the sugar.

8. Dip a little syrup with chopsticks, then quickly put it into cold water and take it out. If the sugar tastes crunchy and does not stick to your teeth, it means the sugar is ready. If it sticks to your teeth, continue to simmer it over medium-low heat. At this time, you need to pay attention to the sugar, don't let it burn, and stir occasionally.

9. At this time, turn on the minimum heat, add the fried sesame seeds, and stir quickly.

10. After mixing, pour it onto the cutting board, flatten it into a rectangle with a knife, or use a mold to shape it.

11. Then cut into small slices. Cut quickly. The sugar will break into pieces when it is completely cold.

12. The freshly cut sugar should be spread out. The hot ones will still stick together. Just let it cool.
