Oil keeps packed noodles from turning into a brick

If your lunch noodles always come out stuck together, the fix is a quick rinse and a splash of oil before they go in the box.

The problem is surface starch. When noodles cool, the starch on the outside acts like glue. Rinsing cooked noodles under cold water washes the excess starch away, then tossing them with about a teaspoon of oil — sesame, peanut, or even olive — coats each strand so they don’t re-stick. It might feel like you’re adding grease, but you’re actually adding a barrier.

For soup noodles, the bigger mistake is putting hot broth in the box with the noodles. The noodles keep soaking and turn to mush. Pack the broth separately and pour it over when you’re ready to eat. If you’re packing a cold noodle salad or yakisoba, the oil trick is all you need.

And don’t skip the rinse even if you’re eating the noodles cold. Leftover starch is why your fork comes out with one solid clump.

You’re not seasoning the noodles, you’re giving them personal space.
