Spaghetti noodles

Spaghetti noodles are food that Rarity likes.

Cooking
In Episode 1, Rarity gives Twilight instructions on how to make spaghetti noodles.
 * You get the spaghetti noodles.
 * You put them in a box.
 * You put them in the oven.
 * You bake them.

It is unknown if Rarity's steps on how to bake them were correct, judging by how surprised Twilight acted upon learning that you don't put the noodles in water.
