Chestnuts are round and big. When frying in a pot, there is a big gap between chestnuts and chestnuts, and the heating is uneven, which is easy to cause some to burn and some to be immature. Putting sand and chestnuts in a pot to fry together is to use the principle that sand is easy to dissipate heat after being heated. The sand particles are very small and easy to contact with chestnuts, so chestnuts are fried quickly.

At the same time, hot sand can transfer heat to each chestnut, so that chestnuts will be evenly heated and will not be burnt or undercooked.
