Best known today for its wine, the island of Madeira, 625 miles southwest of Portugal, was once a stopover for merchant and slave ships of the “triangular trade,” traveling between Africa, America, and Europe from the 1600s to the 1800s. Many crypto-Jews, called conversos or bnei anusim (the forced ones), lived on Madeira, where they first encountered one of the tastiest items coming from the port of Charleston: corn grits.
Until this New World food arrived, Jews—and most everyone else in Europe—ate gruel or porridge made from chickpeas, beans, barley, rice, or wheat for breakfast, and sometimes dinner. But corn grits changed the menu. (In Italy, these grits were ground a bit rougher, and later became polenta.)
