Callos con EspinacaMy sister, Dorothy Davis, contributed this recipe from her kitchen in Mulege, Baja, Mexico where she and her husband live most of the winter. Dorothy is an artist and spends much of her time drawing and painting, but she has a great interest in Mexican food as well. Scallops are plentiful near Mulege, and fresh produce, including spinach, can be purchased right from the growers.
