Lomo saltado. Hot empanadas and a sweating bottle of Cristal or Quilmes beer. Chupes de this and chupes de that, a small plate of ceviche clásico or ceviche mixto and then, of course, the ubiquitous papas a la huancaina. At Cebiche, most of the menu might seem old hat to anyone who's already discovered the joys of Peruvian cuisine. But for those wise enough to save a little room for dessert, there's something rare and wonderful: picarones. This is kind of like doughnut soup: four deep-fried pumpkin fritters shot through with little pieces of sweet, earthy pumpkin flesh, served swimming in a bath of mile de chancaca, which is like maple syrup without the maple, just pure, raw, glorious sugar. For a normal person, half of one fritter would be plenty; a whole serving is enough to instigate an instant (and well-earned) diabetic coma.
