There are few times when I'll cut my pasta rather than twirl it. And that's when I'm wearing a light colored shirt (such as a white dress shirt), to keep the sause from dripping on it. Yes, I know I just completely ruined a perfectly good plate of italian food, but I'd rather not have red spots on my clothes
And if you have a pot that's too small to boil your pasta without breaking it, there's still a way to properly cook your spaghetti. As the water's boiling, add your spaghetti, and if some of it is in the pot, and some of it is out of the pot, pointing skyward, then that's fine. As the pasta softens from the boiling water, you'll soon be able to curl it all in. Just be certain to stir often to prevent sticking, and you're all set. Uncut spaghetti in a small pot
And always add oil and a dash of salt to the water. This keeps the pot from boiling over, without having to lower the heat on your stove. Olive oil is best, and so is butter.
Damn, now I'm starving
