hazel
And the small ones.
Chinese chestnut
That's more like it. Once I bought a bag of hazelnuts and a bag of small chestnuts at home, and my family wondered why I wanted two bags for one bag.
But I'm not afraid of not knowing the goods, and I'm afraid of comparing the goods. The best way is to taste them. After I give it to my family, they will understand, because hazelnuts are crispy and not so sweet, while chestnuts are soft and sweet.
When you say appearance, there is actually a difference.
The first is color. They are all brown. The hazelnut shell is slightly lighter, like coffee with cream, while the chestnut shell is darker, like milk chocolate.
Secondly, the texture, hazelnut shell is very hard, like walnut shell, while chestnut shell is soft, which can pinch nails.
Then there are lines. There are vertical lines on hazelnuts and chestnuts, but the lines on hazelnuts.
