Heston tackled an American icon that has taken over the world, the hamburger. He started his research at Louis' Lunch in New Haven, Connecticut, where hamburgers have been served since 1898. In New York City Heston does something he hasn't done for over a decade - he eats a Big Mac - before sitting down to chat with top American chef Thomas Keller at his café, Bouchon Bakery. There he enjoyed an inspirational burger made from wagyu beef encased in a buttery brioche. Back home he got to grips with blending three cuts of beef and comes up with a unique method for grinding that really will make your burger melt in the mouth.
