How to make a perfect Five Guys burger

Prep time: 5 minutes. Cooking time: 5 minutes. Servings: 2.

The hardware

80/20 chuck, about ¼ pound
90/10 sirloin, about ¼ pound
2 sesame seed buns
4 slices Kraft American cheese, deli style
ketchup
mustard
hot sauce
mayonnaise
2 cooking areas (one for buns, one for meat)
non-grease parchment paper
cookie sheet
food scale
aluminum foil

The process

Mix even proportions of chuck and sirloin. Make 4 meatballs, weighing 3.3 ounces each. Flatten balls between nonstick parchment paper.
On different grills, simultaneously start cooking burgers on medium-high and toasting buns on medium-low. At 30 seconds in, flip and flatten burgers.
When buns are lightly toasted, remove from heat. Coat top bun with generous helping of hot sauce and mayo. Coat bottom bun with 3 rings of ketchup and 2 rings of mustard.
About 2 minutes after the first flip, flip burgers again and flatten to your liking. Flip again 2 minutes later, flattening again.
Top each patty with 1 slice cheese. Put 2 patties together cheese to cheese, and place stack between buns.
Wrap burger in aluminum foil. Keep wrapped for at least 1 minute, then unwrap and enjoy.
