What is the sand for roasting chestnuts called?

The sand used for frying chestnuts is quartz sand. You should choose larger particles. After repeated frying, the sand will be ground smooth and have no edges.

Generally, in order to make the fried chestnuts have good color, aroma and taste, chestnut roasters often need to "cultivate" the sand.

While frying the sand, maltose, honey, vegetable oil and the attachments on the chestnuts are added. After high temperature heating, the sand gradually turns black.

Why do we need sand to stir-fry chestnuts?

Since the specific heat capacity of iron (the amount of heat absorbed when the temperature rises to a certain level) is small, the iron pot itself absorbs a small portion of the heat and conducts heat quickly; on the contrary, the chestnut shell has a large specific heat capacity and a low thermal conductivity. Therefore, most of the heat is absorbed by the chestnut shell, and only a small amount of heat is conducted to the inside of the chestnut shell to heat the chestnut kernel.

The mass of the stone is very large, and its thermal conductivity is between that of the iron pan and the chestnut shell. It can absorb a large amount of heat without the temperature rising too quickly, so the chestnut kernels have enough time to be fried at a suitable temperature.

During the chestnut frying process, the stones must be turned over constantly to ensure that the chestnut shells are heated evenly in all directions. In addition, turning the stones can allow for more complete contact between the stones and the chestnut shells, helping to improve heat transfer efficiency.

What can't chestnuts be eaten with?

Many people may not know that chestnuts cannot be eaten with beef. They feel that these two foods do not seem to have anything to do with each other, and they do not think there is any conflict between them. However, the vitamins in chestnuts can easily react with certain elements in beef, which will not only reduce the nutrition, but may also cause diarrhea and vomiting.

Chestnuts cannot be eaten together with almonds. Although they are both dried fruits, eating them together may cause stomach pain. This is because almonds contain a lot of oil. Eating too much of them may cause physical discomfort. In addition, eating chestnuts can cause indigestion, which will cause stomach pain.

Chestnuts cannot be eaten together with tofu. Eating chestnuts and tofu together will destroy the nutrients of both and will cause a reaction that easily produces harmful substances. If you eat them like this often, you are prone to stones, so don't eat tofu when eating chestnuts.

Don't eat mutton when eating chestnuts. Chestnuts are originally hot foods. Eating too much can easily cause getting a sore throat. Yang heat is also a hot food. Eating them together is not only difficult to digest, but also easily causes getting a sore throat, so don't eat them together.

Chestnuts are very nutritious, and many of the nutrients they contain are much higher than ordinary foods, so eating them has many benefits. Chestnuts can not only be used as snacks, but can also be eaten with many foods, and they are delicious no matter how they are cooked, but remember not to eat too much.
