A lot of chefs says that u shouldnt put a lot of ingredients in burger because that will "fuck up" the taste of meat, but thats bullshit imo. I usually put ketchup, tomato, onion, green salad and chili.
Duuuude thats a shitton of ingredients but I like it! Btw whats that thing he put at 0:28? Looks like a thing u put in a soup :/
I remember watching some Italian guy making sandwich, best thing ever, will try to find it.
