We Cooked Burgers for the World Expert

Cooking a burger for a global authority like George Motz requires absolute precision and zero gimmicks. At London's Fallow, chefs Jack Croft and Will Murray demonstrate an approach that focuses heavily on sourcing, texture, and high-heat execution rather than over-complicating the final build. For professional kitchens, their demonstration highlights how simple, classic elements—beef, bun, and cheese—must be executed with technical perfection to stand out in a saturated market.

Sourcing and Grind Mechanics

The foundation of Fallow's burger lies in their commitment to mature ex-dairy beef. Using retired dairy cows provides an intense depth of flavour and rich yellow fat development that younger cattle simply cannot match. When prepping the meat, the fat-to-lean ratio must be kept high to ensure the patty remains juicy when cooked on a screaming-hot flat top.

The grind is equally critical to the mouthfeel. A coarse grind keeps the patty light and tender, preventing the dense, rubbery texture that comes from overworking the minceMinceTo cut or process food into extremely small pieces.. Chefs should handle the seasoned beef as little as possible when portioning and forming the patties. This prevents the warmth of the hands from melting the fat prematurely, which can ruin the texture and cause the juices to run out during cooking.

Plancha Technique and Heat Control

Bun preparation is treated with equal weight. Toasting the bun in butter or rendered beef fat creates a crucial caramelised barrier. This prevents the juices and sauces from soaking into the crumb, maintaining the burger’s structural integrity from the pass to the table. Cheese is added immediately after the flip, using the residual steam from the meat to melt it fully over the patty for a cohesive bite.
