What do wild walnuts look like?

Wild walnut kernels are thin and fragile. The finished products are mostly irregular blocks with wrinkles and grooves on the surface, with different sizes and diameters of 2~3cm. Walnut peel is generally light yellow or yellowish brown, membranous, the vascular veins in the middle of the pulp are dark brown, and the cotyledons are white.

Wild walnut fruit is crisp, oily and sweet, with no strong odor and refreshing taste. But the peel on the surface of walnut kernel is bitter. If raw walnuts are not peeled cleanly, it will greatly affect the taste, which is also the main reason why walnuts are regarded as astringent by consumers.
