Cashew nuts are a popular snack all over the world. But not many people know that they are actually the seeds of the cashew fruit. The cashew fruit is native to Brazil, but today it is grown in many tropical countries. The cashew tree is a small evergreen tree that can grow up to 20 meters tall. The tree has a short trunk and a dense canopy of leaves. The leaves are dark green and leathery. The flowers of the cashew tree are small and white. The fruit of the cashew tree is called a cashew apple. The fruit is actually the swollen stem of the flower. The fruit is yellow or red, and it has a strong, sweet smell. The flesh of the fruit is thin and full of juice. The cashew apple is not eaten raw because it contains a poisonous substance called urushiol. This substance is also found in poison ivy and poison oak. The cashew apple is used to make jams, jellies, and wines. The cashew nut is the seed of the cashew fruit. The nut is encased in a hard shell. The shell is poisonous and must be removed before the nut can be eaten. Cashew nuts are a good source of protein, vitamins, and minerals. They are often used in Indian and Thai cuisine. Cashew nuts can be roasted, salted, or cooked in sweet dishes. If you are looking for a healthy snack, cashew nuts are a great choice.
