About Walnut
Walnuts are a highly nutritious and popular nut, prized for their rich flavor and health benefits. Native to regions across Asia and Europe, they have been consumed for thousands of years. The walnut tree produces a hard-shelled fruit containing the edible kernel we know as the walnut. Walnuts are commonly eaten raw, roasted, or used as an ingredient in baked goods, salads, and savory dishes. They are an excellent source of omega-3 fatty acids, antioxidants, and various vitamins and minerals, making them a healthy and delicious addition to any diet. They are also used to create walnut oil.
Size Overview
A standard walnut is about the size of a golf ball, fitting comfortably in the palm of your hand. Its roughly spherical shape typically measures around 40mm in width, 40mm in height, and 40mm in length. That's equivalent to 4.0cm x 4.0cm x 4.0cm. Considering these dimensions, a walnut is a relatively small nut, easy to carry and store. When trying to estimate the amount of walnut needed for a recipe, keep these walnut dimensions in mind to gauge how many you need!
