I'm intrieged by a technique that I saw twice before. The technique envolved using a whipping siphon to airate bread batter and then cooking the batter.
The first time I saw it , the chef mixed a batter , added it to a whipping siphon and then sprayed a layer of airated batter on a cookie sheet and baked a sort of a bread "sheet" if you can call it that.
The second time I saw it by chef tyler florence in his instagram account. He used a mold on top of a griddle and sprayed the batter inside the mold to make a burger bun.
I tried looking everywhere for anything remotly similar but couldn't find any topics on the subject.
