As you fire up the grill this Memorial Day, you may want to take a moment to pay homage to the people who first brought you the hamburger. There is a lengthy and fascinating article on the history of the hamburger on What's Cooking America. While there is some debate about who created the first hamburger, Louis' Lunch in New Haven, Connecticut has a strong claim to the title.
According to What's Cooking, "Louis ran a small lunch wagon selling steak sandwiches to local factory workers. A frugal business man, he didn't like to waste the excess beef from his daily lunch rush. It is said that he ground up some scraps of beef and served it as a sandwich, the sandwich was sold between pieces of toasted bread, to a customer who was in a hurry and wanted to eat on the run."
You can still get hamburgers today at Louis' Lunch. However, don't expect to get any ketchup. The Louis' Lunch website states that their hamburgers "have changed little from their historic prototype [and] are still the specialty of the house. Each one is made from beef ground fresh each day, broiled vertically in the original cast iron grill and served between two slices of toast. Cheese, tomato and onion are the only acceptable garnish -- no true connoisseur would consider corrupting the classic taste with mustard or ketchup."
