Roger heads to Northern California for two spectacular wood-fired Mediterranean seafood feasts. In Napa Valley, the Seltzner family is famous for their wines and their towering outdoor oven called the Infiernillo. Hot coals are placed on the top and bottom of the Infiernillo and the food is cooked in between. Roger helps encase whole fish, potatoes and onions in salt before they're baked in the enormous oven. In Tomales Bay, caterer Tom Meckfessel prepares a delicious surf-and-turf Spanish-inspired paella over a wood fire right on the water. Roger harvests local clams with John Finger, owner of Hog Island Oyster Farm, which is one of the key ingredients for the mouthwatering paella.
