How do you distinguish between different varieties of nuts?

There are many types of nuts, and each nut variety has its own characteristics. To distinguish the varieties of different nuts, we can identify them from the appearance, taste, etc.

First of all, appearance is one of the important bases for distinguishing various nut varieties. The walnut shell is full brain-shaped, with irregular lines on the surface; Almonds have a distinctive flattened ovate shape with a smooth surface; The shell of the cashew nut is a fruit with protrusions, shaped like a small heart; Pistachios, on the other hand, are semi-open fruits with nuts inside. The variety of various nuts can be preliminarily judged by the appearance.
Secondly, taste is also one of the important characteristics that distinguish nut varieties. Walnuts have a harder shell and the kernels are full and hard; Almonds have moderate hardness and a crispy taste; The taste of cashew nuts is softer and fragrant; Pistachios, on the other hand, have a sweet and savory taste. Through the experience of taste, it is also possible to distinguish the varieties of various nuts well.
In addition to the above aspects, factors such as the origin and planting environment of various nuts can also help us distinguish varieties. For example, walnuts are mainly grown in China and the Americas; Almonds are mainly produced in the coastal regions of the Mediterranean; Cashew nuts are mainly produced in regions such as Africa and India; Pistachios are mainly produced in the coastal areas of the Mediterranean. It is also possible to distinguish the varieties of various nuts by knowing where they are produced and the environment in which they are grown.
In general, to distinguish the varieties of various nuts, we can consider many aspects such as appearance, taste, and origin.
