Walnuts

Walnuts are round, hard-shelled nuts with a wrinkled, brown exterior and a slightly bumpy surface. The shell encases two halves of edible kernels, which have a unique brain-like appearance with deep grooves and folds. The kernels are light brown to golden in color, with a slightly oily texture. Walnuts have a rich, earthy flavor with a hint of bitterness and a satisfying crunch.
