What is your favorite hamburger size and whatever you put on it?

I love Fuddruckers!

If I make them, I make them palm sized, like they're meant to be. Restaurants make them stupidly big. I also don't use buns. They're too big. I use regular bread or sandwich thins. Served without fries.

I put mustard, mayo, ketchup, lettuce, onions (cooked and raw), pickles, beetroot, tomato, cucumber. Sometimes an egg.

Though if I'm honest, if I order it when I'm out, it's really only for the fries. It's my go to long haul flight food, even though you're not meant to eat a heavy meal while flying. I barely eat on the 15hr flight and this gets me through the next eight to ten hours.

Fast food.
JITB $6 burger.
At home.
Good beef, sesame buns ( toasted )
Lettuce, onions, tomatos, avocado, dill pickle, sharp cheddar, mayo, ketchup, good mustard, tapatio.
Bacon makes anything better.

6oz Ground sirloin, grilled medium rare on a roll.
Top with carmelized onions, cheddar cheese, and bacon (bbq sauce optional). No ketchup!
Perfection.

From the mind of an American chef.
Butter and toast the inside of your bun. Cook your half lb of ground beef medium. Stack it in this order: bun, ketchup, meat, cheese, lettuce, tomato, mayonaiise, bun.

That is how it is done. Feel free to add onion, avocado, and/or bacon.

Ideally a blend of short rib, brisket and Chuck. 80/20 protein/fat.

You're welcome Euro's that can't get it right.

I like 1/2 pound burgers from Firestone brewery. Love katsup, onions, lettuce, and pickles
I also like the double double from in and out burger with everything on it but thir buns are made cheap!
The better buns make the burger better. Real beef burgers are better.

Pineapple , Crumbed fish , Lettuce, Sweet Mayo and Grated Cheese.

Big mac and homemade is best.
But Burger king sells the perfect burgers compared to MC Donalds- their burgers are flat like somebody purposely squashed them.
