hello! I'm Italian!! the way they cook in this drama is true! i cook like this at home too!! while pasta is getting ready, i prepare the sauce. the tomato sauce for pasta (if you want to cook italian style^^) is not just the tomato sauce or ketchup (MY GOD, THIS IS ERESY FOR ITALIANS)
first i put olive oil, when it is hot i add cutted onions. when they're gold (not burned^^') i add the sauce.
in reality, the more the sauce cooks, the better it tastes! (for example, when i make RAGù i cook it for 2 hours or more!)
Matsumoto Jun is a really good cook!! i'll be glad to exchange recipes with him!!
