This is a filler episode probably inspired by the omake.
So, Rin was culture-shocked that the school cafeteria serves first class cuisine. Problem is that you need a lot of money to buy those food. In True Cross Academy, not everything is free unlike Hogwarts. So, Yukio though of an option: cook your own food.
Rin like this idea since not only he’s good at cooking but guys who know how to cook are popular. And Yukio has a sneaky way to avoid those annoying fangirls who want him to taste the bentos they made. Anyway, you can see that Rin is a good cook and housewife. XD
