Pasta is a staple in my diet, and spaghetti with my favorite tuna-tomato sauce is something I eat pretty much weekly. There are only 2 people in my household, and while we sometimes have people over and/or want to cook enough pasta to have leftovers, often we just want enough to feed us for that night. On those nights it seems silly (not to mention wasteful of water and energy) to fill our big dutch oven with water in order to cook a small amount of pasta. However, the dutch oven is the only pot we have that long pasta fits in without breaking it.
I've heard that you're not supposed to break pasta (my boyfriend nearly fainted the first time he saw me do it), but no one seems to be able to explain why. Can you break pasta? If not, how are you supposed to cook a small amount of pasta without using a huge pot?
