Davy shows a foolproof way to assure they puff precisely by slicing thin regular potato chips and gluing them together with corn starch and egg white.
Why even do this?
For fun! And for interest. They're little mind-blowers right there. Because you're so ace.
I find Davy interesting to watch. He seems a bit awkward as teacher and presenter. When he looks up his cosa nostra eyes turn sanpaku. He has an unusual interest. His channel is loaded with instructions for unusual sushi, mosaic style, colored sushi, sushi that forms little pictures inside them when cut, like a panda, sushi made with vegetable sheets, sushi with black rice, no-rice sushi, How to carve carrot into a leaf shape and molded fried egg in whipped white that keeps its shape only three minutes, odd things that are interesting but not all that useful. He has a very good deal of extremely refined technique, most all of it Asian. His speech is unusual and his accent and pattern do not match the place where he's from suggested in his other videos. I like unusual characters.
