Hamburgers

- 1 pound (450 grams) ground beef chuck or round
- Salt and fresh ground black pepper
- Butter or oil, as needed
- Take the beef out of the refrigerator and allow it to sit at room temperature for about 5 minutes before forming the patties.
- Form beef into three 5 to 6 ounce hamburger patties. Use your thumb to imprint a dimple into the middle of each burger. (This prevents the middle of the burgers from puffing up while cooking).
- Season both sides of the hamburgers with salt and pepper.
- Put 1 tablespoon oil or butter in a cast iron pan over medium heat. Cook hamburger patties 3 to 4 minutes on each side, depending on how well done you like it. Burger Doneness: Rare = 120 degrees F; Medium-Rare = 130 degrees F; Medium = 140 degrees F; Medium-Well = 150 degrees F; Well Done = 160 degrees F
- Rest burgers covered loosely with aluminum foil for 5 minutes then serve on a buttered bun with lettuce, tomatoes and onion (or how you like it).
