Description
Walnuts are edible seeds from the trees of Juglans genus. They are round, single-seeded fruits of the walnut tree. The fruit and seed of walnut are enclosed in a thick, inedible husk. The shell of the fruit that encloses the kernel is hard and two-halved.
Walnuts have a delicious taste and crunchy texture, which is why they are used in many desserts and baked goods such as cookies, cakes, granola, cereals, energy bars, and the ever-popular banana walnut bread. The nuts have always been considered as ‘brain food’ perhaps because the surface structure of the walnut has a wrinkled appearance, like that of the brain.
