The main reasons for the failure of homemade candied haws in the microwave are as follows:

1. Failure to control the temperature and time of the sugar. Temperature and time are very important factors when making candied haws. If the temperature is too high or the time is too long, the sugar will melt too quickly and the resulting gourd will not be complete and beautiful. On the contrary, if the temperature is too low or the time is not enough, the sugar will not melt enough and the resulting gourd will be too hard.

2. The candy is not evenly spread. In the process of making candied haws, spreading the sugar evenly on the surface of the fruit is a very important step. If the coating is uneven, the surface formed by the candies will be uneven and the uniformity of heating will be affected, resulting in poor shape and taste of the candied haws.

3. Uneven heating. The heating method of microwave oven is microwave heating. Due to the characteristics of microwaves, they may produce hot and cold spots during the heating process, which will affect the production of candied haws. If the heating is uneven, the surface created by the candy will be uneven and may even appear burnt.

4. The spines surrounding the fruit are too thick or too thin. In the process of making candied haws, the thorns used to wrap the fruit also need to be paid attention to. If the thorns are too thick, it will be difficult to spread the candy evenly on the surface of the fruit, causing uneven adhesion of the candy and affecting the appearance of the candied haws. On the other hand, if the thorns are too thin, it will be difficult for the candy to stick to the thorns, causing the production to fail.

In short, there are many reasons why homemade candied haws in a microwave oven fails. To successfully make delicious candied haws, you need to master the temperature and time of the sugar, pay attention to the even spreading of the candies and the uniformity of heating in the microwave, and choose the right spines to wrap the fruit.
