I agree that what makes a great burger begins before it hits the bun. I only use lump or natural charcoal, never that kingsford crap thats made from soft coal and petroleum products. In fact, I used to make my own charcoal.
Edit to add: 80/20 ground chuck is my preference... any more fat and shrinkage is an issue, any less fat and it might as well be called a Sahara Burger, bone dry for 1500 miles.
Then I always smoke them with pecan wood as soon as they go on the grill. It only takes about 2 minutes of heavy smoke to impart good flavor. I flip them at 2 minutes, ready after 2 more minutes. This gives me a medium to medium rare burger with a nice crust, depending on how hot the coals are.
Afterwards a toasted bun, onion, sometimes lettuce but not much, sometimes cheese, never tomato. Condiments… mayo on the bottom bun, mayo prevents the bottom bun from soaking up the burger juices. It’ll stay together as you eat and not be soggy. A little ketchup on the top bun, then pickles on the side.
I've had a few great burgers at burger joints... always locally owned, hole in the wall places... The best one was at a mom & pop place 1 block west from Anderson Hospital in Houston, don't remember the name, ate there every other day for 3 months... fantastic burger.
@havasu thanks for the reminder... the best chain burger I ever had was at In-N-Out Burger. Haven't had one since the 90's, they were great back then.
Where I live now... I make a better burger than I can buy in my area... I eat burgers at home for that reason.
