Ingredients:

Burger Sauce

• 1/2 cup mayo

• 1/4 cup yellow mustard

• 1/4 cup ketchup

• 1 Tbsp vinegar

• 4 Tbsp sweet relish

Burgers

• 1lb ground beef

• 2 Tbsp Worcestershire Sauce

• salt and pepper to tasted

Extras

• brioche buns

• american cheese

• pickles

• lettuce

• red onion

• tomato

Instructions:

Make the burger sauce: 

1. combine all ingredients in a bowl and stir until combined. Adjust to taste. Should resemble in-n-out sauce.

Make the Burgers

1. mix ground beef with salt and pepper and form into 4 balls.

2. Butter the buns and toast them on your skillet or griddle until golden.

3. Prep the toppings.

4. Cut a small piece of parchment paper that you’ll use on top of the burgers to prevent sticking.

5. Heat a cast iron skillet or flat griddle until it’s very hot; place a few of the burgers on the hot surface. Sprinkle them with a big pinch of salt and let them sit and sizzle for about 20 seconds. 

6. Place the parchment paper on top of each burger and then, using a heavy, flat tool, press the burgers down as flat as you can get them in one swift motion. They’ll be super sizzly and splattery, but they should make a nice, round, thin smash burger shape on the griddle. Cook for a few minutes and then flip and top with cheese right away.

7. To melt the cheese quickly, cover pan with lid until cheese has melted.

Assemble Burgers

1. Spread top and bottom buns with burger sauce, place a burger, and top with desired toppings.

2. Serve with fries and enjoy!
