Huitlacoche or (equally tricky to pronounce) cuitlacoche is a black, bulbous fungus that grows on corn. It looks revolting and distantly related to The Blob, so I can only assume that some poor Aztec thousands of years ago must have been either starving or being subjected to punishment when he first tried it. Famished daredevil or criminal, whoever was the first to eat it made a wonderful discovery. Sometimes referred to as smut, huitlacoche has also picked up a swankier moniker: corn truffle. Smut or truffle, huitlacoche is earthy, velvety, and intensely rich. In Mexico it’s sold canned at the grocery store (often with chiles and onions), but lucky for you, you don’t have to book a ticket to the D.F. to get it — simply order a few tins on Amazon with your next book or DVD purchase. It’s surprising, unexpected, and luxe layered in a quesadilla, stuffed into fried squash blossoms, wrapped inside crêpes, or tossed with pasta.
