Feliz cumpleaños!! Happy birthday!!! I really really love reading your story's on ao3!!! I love sheith!!! So i have heard people saying that shiro is a terrible cook but! I headcanon that he is only a bad cook just when he is cooking a dish that isn't Japanese becouse his grandma only taught him that tipe of kitchen. (Sorry if I made a grammatical mistake english isn't my first language and I'm still practicing) ☺
Oooh, I LOVE that idea. I like to think that Shiro was really close to his family, especially the women in his family. His grandma was probably super duper tiny, which makes it better since Shiro’s over 6 feet tall, and fierce enough to kick anybody’s butt if she had to. She was a woman who knew what she wanted, she led her family through hard times, and she always made sure that her grandson could follow his dreams of reaching the stars, no matter what sacrifices they had to make along the way.
Cooking together was probably one of Shiro’s favorite activities. She made sure that he was grounded and in touch with his heritage, it was important to carry a piece of who they were as people out into space. On festivals, he was probably tucked right under her elbow learning how to make foods and if he had the right ingredients, he could whip up a celebratory Japanese dinner no problem. The only thing is, all that practice doesn’t really translate in a world full of ovens and microwaves and whatever high tech cooking devices they’ve got now.
I’m also 100000% certain that she’s the one who taught him that patience yields focus when they were cooking together. Don’t rush the process and take care with every step to achieve your result.
