Mama was a natural cook. At harvest time, she would whip up a noontime dinner for the men in the field: fried chicken with milk gravy, ham, mashed potatoes, lima beans, field peas, corn, slaw, sliced tomatoes, fried apples, biscuits, and peach pie.
Out of the thirty thousand types of edible plants thought to exist on Earth, just eleven—corn, rice, wheat, potatoes, cassava, sorghum, millet, beans, barley, rye, and oats—account for 93 percent of all that humans eat, and every one of them was first cultivated by our Neolithic ancestors.
