Roger heads to the heart of New Mexico where cooking with fire is taken to new culinary heights with mud and steel. Roger visits Comida de Campos in Embudo, a farm and cooking school where delicious feasts are cooked in cone-shaped clay ovens made from mud. He'll help season pork shoulder with spices, wrap it in burlap and then cook it over a bed of corn in the oven. In Bosque, Roger fires up three steel discos and one large jara for two New Mexican pork dishes: carne adovada, which is pork slowly cooked in a red chile sauce, and carnitas where the meat is cooked in cola, citrus and spices.
