The Hamburger Bun is a soft bread roll. By adding
meat, lettuce, tomato and condiments to the sliced
in half bun, you get a “hamburger”. The first person to
serve a hamburger on a bun was most likely Oscar Weber Bilby, who
served a ground meat patty on buns baked by his wife, but they were
more similar to a roll and not necessarily a true Hamburger Bun. It is
generally accepted that the modern Hamburger Bun was invented
in 1916 by a cook named Walter Anderson. He is credited with creating
the modern grill. Hamburger Buns are designed to be round yet flat.
They are typically wider than they are tall, and can therefore more
easily hold the hamburger patty and toppings, without adding too
much extra height.
