As said by Samwise Gamgee in The Two Towers, the second movie in The Lord of the Rings trilogy based on J. R. R. Tolkien’s famous epic fantasy: “Potatoes, mash ’em, boil ’em, stick ’em in a stew” after Smeagol complains of him ruining their supper of scrawny rabbit with vegetables. Despite its humble place, the potato remains a most versatile and beloved vegetable that occupies an integral part of the human diet as the world’s fifth most important food crop after wheat, corn, rice, and sugarcane.
