The white walnut tree, also known by its scientific name Juglans cinerea, is native to eastern North America. This tree produces a fruit that is commonly referred to as a white walnut or a butternut. However, there are other synonyms for this nut, such as oilnut, butter nut, and white walnut hickory. The white walnut is similar in shape to a regular walnut but has a distinct flavor that is more mild and buttery. The nut can be enjoyed raw, roasted, or as an ingredient in various recipes such as salads, pastries, and even beverages.
