If hawthorn cake is not solidified in the production process, it is usually caused by insufficient sugar or no gelatin powder added. Sugar plays a solidification role in hawthorn cake, while gelatin powder can increase the consistency and solidification of cake. If the hawthorn cake is not solidified, it can be repaired by returning to the pot. When returning to the pot, you can add a proper amount of sugar and gelatin powder, and then reheat and stir them to fully dissolve and mix them. Through this treatment, sugar and gelatin powder will play a role again, so that hawthorn cake can be solidified and formed.
