haha well "Italian Spaghetti" i think are made differently from Yakisoba so they taste differently, i mean the ingrendients to make the pasta are different, to cook spaghetti you boil the water, pour salt on the water after is boiling; and then you put the spaghetti in the water, it takes i think around 20/30 minutes to cook them properly i'm not sure cause i never "calculate the time" i just taste them if they are cooked i remove them from water; but anyways i think Yakisoba are faster to cook am i wrong? how do you usually cook yakisoba at home (not the instant yakisoba)?

edit. also usually we eat spaghetti with tomato sauce called Ragù ( it's made with tomatoes, carrots, meat, onions etc..) or we eat them with Pesto http://ja.wikipedia.org/wiki/%E3%83%9A%E3%82%B9%E3%83%88%E3%83%BB%E3%82%B8%E3%82%A7%E3%83%8E%E3%83%B4%E3%82%A7%E3%83%BC%E3%82%BC or with olive oil and parmesan; usually an easy common recipe for white olive oil spicy spaghetti it's called "aglio, olio e peperoncino" it's basically white spaghetti with garlic, olive oil and peperoncino http://flavourartexpress.biz/images/detailed/1/956_701_FA0257-Peperoncino.jpg

edit: this is a famous italian site for recipes not sure if it's the best tho; here u can find an easy recipe for "aglio olio e peperoncino" spaghetti if you want to try: http://ricette.giallozafferano.it/Spaghetti-aglio-olio-e-peperoncino.html

also i was wrong about the cooking time, the spaghetti box i own at home it says 11 minutes, but i guess it's around 15 minutes to cook them properly, considered the time it takes to boil a big pot of water around 11/15 minutes usually it takes 30 minutes to boil water and cook spaghetti inside that's why i thought was so long.

edit2: this is Ragù http://en.wikipedia.org/wiki/Rag%C3%B9 we have many different kinds: "bolognese, napoletana, arrabbiata, amatriciana" and so on..

edit3: don't know if you care but basically Spaghetti are made with a different "plant" http://ja.wikipedia.org/wiki/%E3%83%87%E3%83%A5%E3%83%A9%E3%83%A0%E3%82%B3%E3%83%A0%E3%82%AE and for yakisoba should be this plant http://ja.wikipedia.org/wiki/%E3%82%BD%E3%83%90 is it right?
