Must I store uncooked pasta in an airtight container?
It's usually fine to keep the pasta in an open container. But there are two potential issues:


First, if you live somewhere with a very humid climate, the pasta could get unpleasant after many months of storage.
Second, you'll be surprised what weevils like to eat! Keeping anything with even a small amount of starch sealed away makes sure that, if you happen to get an infestation, they won't make a hidden nest in the pasta box.


If neither of these issues bother you, you can use any convenient container without caring whether or not it's airtight.
