CheeseSteak History and Philly Lean
Real cheesesteaks are cooked fresh, covered with American cheese, provolone or Cheese-Wiz and rest in a roll dripping with grease. Sound disgusting? You’re obviously not from Philadelphia. Cheesesteaks were invented in South Philadelphia in the 1930’s at Pat’s Steaks, located in the heart of South Philadelphia.

They were originally topped with a pizza sauce, (now called a pizza steak). There are a number of things you need to consider in your search for the perfect cheesesteak. First, there’s the cheesesteak itself. As already noted, a proper cheesesteak is made with real beef — fresh, not frozen. It is cooked on a grill using grease. As it is cooked, it should be chopped to bits. You then choose which cheese you prefer and whether you want onions. When the sandwich is served the juices should drip from your cheesesteak. In order to avoid ruining their clothes, Philadelphians have learned, what is referred to as, the “Philly Lean”, bending forward to eat the cheesesteak, instead of bringing it to your mouth.
