This is how I make my smash burgers.
If I have time, I will make home-made buns (here’s the recipe that I translated to Spanish from Joshua Weissman).

I make balls of meat and cook them on the griddle at high heat. I use a sturdy spatula to smash them. I add freshly cracked black pepper and salt on the raw side while they are browning, then flip them, add American cheese, and finish cooking them until the cheese is melted.

For the secret sauce, I use:
- Mayonnaise, ketchup, and mustard in the same amount.
- A bit of dill pickle juice.
- Dill pickles, chopped.
- A bit of onion powder.
Then I just make them with:
- Secret sauce.
- Burger and cheese
- Chopped white onion
- Extra pickles
- Optionally, chopped iceberg lettuce.
