Rosquillas de San Isidro are Madrid's May ring biscuits, sweet and lemon-glazed (listas) or matte and aniseed (tontas), peaking on May 15, the feast of the city's patron saint.

Rosquillas de San Isidro descend from the medieval Castilian rosquilla tradition, with the Madrid version becoming canonical in the 18th century. Four types exist: tontas (matte, aniseed), listas (lemon-glazed), de Santa Clara (white meringue) and francesas (sugar-dusted). The biscuits appear in Madrid bakeries from late April through mid-May, peaking on May 15, the feast of San Isidro Labrador. The Pradera de San Isidro picnic on May 15 still draws thousands of locals carrying boxes of rosquillas, tortilla, empanada and a bottle of Valdepenas. La Mallorquina on Puerta del Sol and Horno de San Onofre produce the city's reference rosquillas.
