A member of the Solanum family of plants, the potato originated in South America where many hundreds of distinct varieties are now cultivated. Only a few varieties are grown in other parts of the world, but baked, boiled, steamed, roasted, or as chips or crisps, they are a food that is, in some form, a part of the diet of literally billions of people.
