Pay de LimónPastries and other sweets are often eaten in late afternoon for marienda, a convivial time when people sit and enjoy pastries with coffee, tea, or hot chocolate. In the Zona Rosa of Mexico City, one of the main commercial districts in the city, I often take marienda at the Salon de Te, where I encountered a delicate lime pie very much like this one. To add color and elegance to the pie, sprinkle finely grated lime rind on the whipped cream, or add a few candied violets.
