Title: Cooking
Minato had a phase where he tried to learn to cook (Kakashi suspect the thought process was something like "I married Kushina (Insert hearts in his eyes here)! I'm a married man (Remplace it with dopy smiley now)! Wait as a married man I must provide for my family… But Kushina will kill me if I tried to pay for all the expenses… Wait maybe if I cook for her (and Kakashi)… Yes I will prove that I'm the best husband as she already is the best wife (Imagine a combo of hearts + dopy simley)!"). It went badly for everyone tasting it. They're still a rumor among the Anbu that T&I tried to recreate the fourth Hokage's cooking to use it on prisoners (It's true).
Kushina only effort in cooking was to create a jutsu to reduce the time it take for heating instant ramen. And then making Minato teach her the Flying Thunder God Technique to go to Ichikaru as soon as she was hungry.
Kakashi learned to cook in self-defense (and also ask Minato to teach him his signature technique because it was cool).
