Here is some trivia

What about talking about toppings you have to put on the burger
Here are some
Ketchup
Mustard
The classic: go with Dijon, whole grain, brown, or good ol’ yellow ballpark mustard.
Tangy stuff
Next, you’re going to want a little zip: relish, sliced pickles, or spears running the length of the bun, Chicago-style, are all great. Sauerkraut is in this family too, as is its Korean cousin kimchi. Coleslaw is an unexpected riff that gives you a little crunch and a little cream, too.
Creamy things
Mayonnaise is a classic option, especially in other parts of the world, and if you’re feeling fancy you could flavor it with a bit of chipotle, wasabi, miso or sriracha first. Other great creamy toppings include avocado (mashed, sliced, diced), sour cream, or even a fried egg.
