Trying to recreate a flavor!

So I recently tried to recreate a flavor of a particularly well liked burger from a particular burger store.

it was according to the internet a simple recipe:

beef with garlic flakes and white pepper

sliced and browned sesame seed bun

Pickles tomato sauce and american mustard raw white onions sliced and american cheese.

The finished burg
Deconstructed burg

Tasted really good, but not as similar to the real thing as I would have liked. and after all the ingredients were calc’d in it was as expensive if not more expensive than just buying it from the store which surprised me.
