Is chestnut a fruit?

The taxonomic status of Castanea mollissima is angiosperm, dicotyledonous, Dianthus subfamily, Fagaceae and Castanea. Chestnuts were first seen in the ancient book The Book of Songs. It can be seen that the cultivation history of Chinese chestnut has a history of at least 2,5 years in China.

Four practical ways to stir-fry chestnuts with sugar:

1. Taste chestnuts with your mouth

Before buying chestnuts, you can find a vendor to taste them. Stir-fried chestnuts with saccharin are sweet at first, but there is no aftertaste. You can taste the bitterness if you taste it carefully. And fried with sugar, basically no bitterness.

2. Hand rubbing

Wipe paper towels when buying chestnuts, take some paper towels with you, and clean the chestnuts first. If you find oil stains on it, it means that paraffin oil may have been added to this chestnut (some people add vegetable oil when frying chestnuts, but the amount added is very small), so it is best not to buy it.

3. Look

Look at the color of the pulp. When buying chestnuts, don't blindly pursue the white or golden color of the pulp. Too golden pulp may have been chemically treated. On the contrary, don't worry if you find that the pulp is brown in the middle after frying or cooking. This is caused by the "browning reaction" of enzymes contained in chestnuts. As long as the taste has not changed, it is harmless to human body.

4. Pay attention to observation.

pay attention to the raw chestnuts beside you. Pay attention to the uncooked raw chestnuts of the vendors. If the raw chestnut is dark in color, less hairy and shiny in appearance, it means that the chestnut is a little old and it is not recommended to buy it. If the color is light, fluffy and the appearance is dull, it means fresh chestnut. In addition, there is a little trick. Chestnuts with flat sides are often sweeter than chestnuts with flat sides.
