[...hmm...] Well, most of the time. Even when you're following a recipe, sometimes you make mistakes, especially if you're worried about making them! [Prime example: Fuuka and her thousands of notes.] But the more you cook the better you'll understand the process and ingredients, until someday you can just improvise. Like Shinjiro-senpai can.

[Truthfully, she can too to a small extent, but she wouldn't put herself even close to Shinji's level.]
