elbow noodles
Short, curved tube pasta, hollow through the center -- the classic shape for macaroni and cheese, since the curve and hollow catch sauce and cheese better than a flat noodle would. Made from the same durum wheat as other dried pasta shapes.
Buying guidance
Check the bag is sealed with no moisture or stale smell. Elbow size varies noticeably by brand -- larger elbows need a minute or two longer to cook and hold more sauce per piece, so match cook time to the box rather than assuming a universal timing.
Substitutions
- Small shells or cavatappi -- similar sauce-catching curves and hollows; interchange by weight.
- Penne or ziti -- larger tubes with a similar sauce-holding hollow, firmer bite, bigger pieces.
- Any short pasta shape -- works in a pinch; cook to that shape's own package time.
Tips & common mistakes
The hollow tube traps water inside each piece, so noodles that look well-drained in a colander can still release extra water into a sauce for the first minute or two after mixing -- let them sit a moment and shake the colander well, or the sauce will seem thinner than it should.
Storage
Plain dried pasta like this has no egg or fat to go rancid, so a sealed, dry package holds good quality for a year or more past any printed date -- it's one of the more forgiving pantry staples as long as it's kept away from moisture and pests.
