I have no stand mixer, so I am cheating here; I was watching my friend doing these, at least he let me roll one of the buns! We also had no pastry brush in the middle of the campsite, so they could even be better.
But, yes, if you want to make top top top level burgers, you will need these buns and a stand mixer. Totally recommended! And they are as good as advertised. Sorry for this terrible photo, buns!
Use for any of the burgers published on lindy.
