Mercado de Comida de Coyoacán

"Think mushrooms only grow in meadows and woods? Think again. Huitlacoche — otherwise known as corn smut, or, more elegantly put, Mexican truffle — is technically a plant disease that spreads into ears of corn but tastes undeniably decadent. The blue-black spores are considered a delicacy, and are best served on huarache or tostadas. Head to the Mercado de Coyoacán just around the corner from the Frida Kahlo museum, for a huitlacoche tostado — or two. And unlike traditional truffle dishes, a huitlacoche tostada will run you less than a dollar." - Travel + Leisure Editors
