What is the fried sand for frying chestnuts made of?

The color of sand itself is not black, but white, because it changes color after a long period of frying. The sand used for frying chestnuts is quartz sand, which is special for roasted seeds and nuts. When preparing sand, clean and even fine sand should be selected, washed with clear water, screened and dried, and then fried with maltose and tea oil to become "cooked sand" before use.

The temperature of fried chestnuts is transmitted by sand. The smaller the sand, the more evenly it is heated. The special sand for roasted chestnuts with round particles has high thermal insulation performance, basically constant temperature, is not fragile and easy to leak, which can ensure the taste of chestnuts to the greatest extent. But after a long time, the sand will become bigger and bigger, and such sand will be eliminated if it can't play its role.
