I wish they hadn't done the "eat the messed food" bit. It's so... old and tired and done to death.
I think they do it at least once in every romcom in the shop. I have read some really old romcoms in my day, hetero for-boys stuff like from 30 years ago, and it's the second or third most used trick when they try to come up with a reason for the cute and popular girl to fall for the dumb nerd mc: she tries to cook something, messes up, but he eats it nonetheless and her heart goes pitter-patter for him. The only ploys that are even more commonplace are "she falls for him after she sees him feeding a stray kitten" and the absolute most popular "she falls for him 'cause one time he did for her some random everyday thing that was kinda nice" which ranks number one in all the charts.
For real, I wish they hadn't used such a silly (un)dead horse trope in a yuri manga that I like. There's no need to go there, dangit: Elsa is already head over heels for Evie and this for a long list of very good motives that have nothing to do with the old tired clichés of shounen romcom.
