the perfect burger v12.0
First, I think 12.1 will be needed with addition of fresh vidalia onion. Could do caramelized as well but I think the fresh sweet onion will work better on this super simple burger.
wagyu ground beef griddled in ghee with 3 slices of american cheese melted (steam) on top. Kaiser roll griddled in butter. Mayo both sides, burger, a little ketchup. I ended up putting some ketchup in a ramekin and knifing small amounts on each bite to get just the right amount of acid per bite. Grease everywhere, it was sublime.
Should have taken a pic before putting the top on, the melted cheese glistened like gold.
