a version of california's iconic in-n-out burger from beach house dinners by lei shishak
For the caramelized onions
2 tbsp unsalted butter
1 large onion, small-diced
2 tsp brown sugar
1/2 tsp salt
4 tbsp water, divided
For the sauce
1/4 cup mayonnaise
2 tbsp ketchup
4 tsp sweet relish
1/2 tsp sugar
For the burgers
4 hamburger buns, sliced
16 oz pickle chips
2 large red tomatoes, sliced
1 small head iceberg lettuce, torn into small pieces
1 lb ground beef
salt and pepper
1/2 cup yellow mustard
8 slices deli-cut yellow American cheese
Melt the butter in a large nonstick skillet sauté pan over medium high heat. Add the diced onion, brown sugar, and salt. Cook for ten minutes, stirring occasionally. Keep an eye on the onion and lower the heat if it begins to burn. Stir in half the water and cook for one minute. Add the remaining water and cook until all the water has evaporated and onions are a nice deep brown color. Remove pan from heat and set aside. Combine all the ingredients in a small bowl. Cover and set aside. Separate the tops and bottoms from the buns. Spread the sauce on each of the halves, followed by a single layer of pickle chips. Additionally, top each of the bun bottoms with a layer of tomato and lettuce. Set aside while you cook the burgers.
