There’s a new kind of fungus you can buy on St. Mark’s Place: Sam Mason, chef of Tailor, is the latest NY chef to curate a corn dog selection at bar PDT; his features huitlacoche, a dank, truffle-tasting fungus a k a corn smut, a k a Mexican Truffle. At PDT, the elaborate hot dog menu (which overflows from the connected Crif Dogs) already includes a David Chang-styled kimchee hot dog and molecular sounding one designed by WD~50 chef Wylie Dufresne, served with fried mayonnaise and tomato molasses. The huitlacoche corn dog debuts this weekend, and is also available on Tailor’s bar menu for $10.
