A nutritionally balanced recipe written with specific instructions. Seems like Iroha's handwriting, but she doesn't recall writing it. She tries making it, but she has no idea, in that moment, who she wrote it for.
A handwritten recipe with detailed annotations regarding nutritional balance.
From its calligraphy, one may think that it was written by Iroha, but she herself doesn't remember.
When trying to cook it, it was a recipe for "for someone's sake" as expected.
The Iroha from that time didn't understand the reason.
