Slopper: A slopper is a cheeseburger, or hamburger served open-faced and smothered in red chile, or green chile (aka chile verde or green chile sauce). Sloppers generally include grilled buns and are often topped with freshly chopped onions. Eating a slopper is no easy task. The use of a fork or spoon is essential, but a fork & knife, or fork & spoon combination is recommended.

Cheeseburger: A cheeseburger is a hamburger accompanied with melted cheese. The term itself is a portmanteau of the words “cheese” and “hamburger.” The cheese is usually sliced, then added a short time before the hamburger finishes cooking to allow it to melt. In fast food restaurants, the cheese that is added to a cheeseburger is typically American cheese, but there are many other variations. Mozzarella, blue cheese, pepper jack, and especially cheddar are popular choices.

Barbecue Burger: A BBQ hamburger is made from ground beef, mixed with onions and barbecue sauce- then grilled on the grill. Once the meat has been turned once, barbecue sauce is  spread on top and grilled until the sauce caramelizes. The bread bun is buttered and also spread with a light layer of barbecue sauce, then toasted on the grill. Anything can be added when building your sandwich -cheese, lettuce, tomato, pickles or sliced onions.

Butter Burger: In the Upper Midwest, particularly Wisconsin, burgers are often made with a buttered bun, butter as one of the ingredients of the patty or with a pat of butter on top of the burger patty. This is called a “Butter Burger.”

Carolina-style: In portions of the Carolinas, a Carolina-style hamburger “with everything” may be served with cheese, chili, onions, mustard, and cole slaw and national chain Wendy’s sells a “Carolina Classic” burger with these toppings in these areas.

Curry Burger: A curry burger is a variant of the American hamburger that is seasoned with curry. Made with ground beef, chicken, or lamb, it is typically seasoned with curry powder, as well as yogurt, onions, green peppers, and other spices, and then served on a traditional hamburger bun.
