♒ - cooking/food headcanon
Despite Reborn’s propensity for acting like he’s infallible, he’s really a mediocre cook. He can cook, but nothing particularly extravagant or special. He can make a mean grilled cheese and a few basic family recipes and he can doctor up some instant noodles, but he can do little else beside. A word to the wise, though: all of his food is spicy. All of it. He has a love of spicy foods, so anything that touches his lips will inevitably have soul-scorching spice to it.
I’d say that this is largely a result of his being a hitman. I mean, he can cook pretty well because A) he watched his mom cook growing up; B) he would try to help his mom out sometimes by trying to cook some; C) he’s had to live on his own for a while and is admittedly too paranoid to trust strangers with the preparation of his food. But, the lack in his ability to cook is due to a lack of natural inclination towards food preparation and a lack of time. He’s near always on the move — staying in one place too long is a hazard — and the job of a hitman is rather demanding.
