Overview: Roger meets two chefs celebrating Argentina's Asado and Brazil's Churrasco in northern California. At Farmstead Restaurant in St. Helena, Chef Stephen Barber built a "live fire" cook area, complete with an eighty-five gallon cauldron, planchas, and metal crosses for Argentinian Asado. Roger and Stephen slow cook spring lamb seasoned with Mediterranean flavors. In Healdsburg, Roger and Mateo Granados, chef of Mateo's Cocina Latina, build an outdoor oven out of bricks and cinder blocks. A large pile of local Manzanita wood is piled in the oven, drizzled with pork fat which serves as natural lighter fluid, and then lit to create coals. Marinated whole ducks, pork loins and leg of lamb are placed onto large Brazilian skewers and cooked on top of the outdoor oven.
