Hamburgers are fucking good, ok? If you don't learn this dish you will never be a successful chef. Even fucking iron chefs get asked to make these things from time to time, ok?
Take raw ground beef and mix in salt/pepper/garlic powder
"Patty out" a hamburger. It should be about 4-5 inches in diameter and about half an inch thick. Any bigger than this and you're making it harder to get an even cooking throughout the burger. Other burgers like the Stuffed Hamburgers take a little different cooking time/technique because of how they are made.
Place in pan heated to medium-high heat and let cook on one side for about 2-3 minutes. A trick for making better burgers is only touching them twice after they hit the pan. Once to flip, and once to take out. This allows a nice sear to develop on the outsides and keep more juices in it. 'NEVER PRESS A BURGER!!!' this releases delicious juices from the burger and into the air. I know you've seen this on movies and such and it looks so cool etc, but don't do it!
After 2-3 minutes on one side (or whenever you think it looks done) flip burger and let it cook on that side for about 1-2 minutes. If your burger is thick and you're worried about the inside being cooked you can put a lid over the pan and this will help the inside cook faster.
When it's done, take out of pan and put onto bun. Congrats, you've just made a Hamburg classic!
