You've been making hamburger patties wrong your entire life
Most home chefs dump their ground beef into a bowl and knead in all the fixings: chopped onion, ketchup, red pepper flakes. Then they roll the dough into balls and flatten them with their hands before tossing them on the grill.
But this method has some major drawbacks.
In a 2007 episode of the short-lived BBC show "In Search of Perfection," Michelin 3-star chef Heston Blumenthal spent six months using science to create the "perfect hamburger." His biggest revelation was that in order to achieve an "open," juicy texture, the grains of ground meat should all fall in the same direction.
There are two benefits to keeping the grains of meat running straight: The first is to avoid the release of proteins that could act as binding agents, and the second is to keep the strings from becoming intertwined. Either could lead to a denser and drier patty.This is when the famed chef's method really veers off the path of the traditional burger patty. Instead of forming patties with his hands, he rolls the entire pile of ground beef into a sausage-like tube using plastic wrap.
Now that's some pretty revelatory stuff.
