Roger Mooking visits the Louisiana bayou for barbecue, brunch and a crawfish boil. In Prairieville, La., he helps a husband-and-wife team of caterers prepare baby back ribs, brisket and 200 pounds of live crawfish. Then Roger heads to Baton Rouge, La., to meet a caterer serving barbecue breakfast sandwiches at a local eatery. They season pork butts and beef cheeks for smoking and then pile the meat onto biscuits with fried eggs, cheese and bacon.
