Cashew nuts are a type of tree nut that grows on the cashew tree (Anacardium occidentale), which is native to Brazil but is now grown in many parts of the world, including Asia, Africa, and Central and South America. The cashew nut is encased in a hard, outer shell that must be removed before it can be eaten.
The cashew nut has a kidney or bean shape, with a slightly curved and pointed end. It has a light brown color, and its surface is smooth and slightly oily to the touch. The cashew nut has a delicate flavor and a crunchy texture, and it is often used in both sweet and savory dishes, as well as in snacks and nut mixes.
In addition to their taste and versatility, cashews are also known for their nutritional value. They are a good source of protein, healthy fats, fiber, and various vitamins and minerals, including magnesium, copper, and zinc. However, they are also high in calories, so it's important to enjoy them in moderation.
