Duche de Leche Cookie Sandwiches (Alfajores)
Variations on this elegant cookie can be found throughout Latin America, but alfajores are associated above all with the cafe culture of Buenos Aires. They're served year-round with coffee, but during the holidays home cooks all over Argentina break out their trusted family recipes—each one unique but always with a decadent filling of dulce de leche sandwiched between two rounds of crisp butter cookie.
