You’ve gone to the trouble of getting rice-flour udon, so you’ll want to finish it in the best condition possible. In this article, we clearly explain how to store rice-flour udon and how to think about its shelf life, covering fresh and frozen noodles separately. Store it properly and enjoy it deliciously to the last bite.
How to Store Rice-Flour Udon (The Basics)
The keys to storage are “the right temperature for the type” and “finishing it within the shelf life on the package.” Storage methods and shelf life differ by product, so first check the package labeling.
Fresh Noodle Type
- Store refrigerated.
- The shelf life is as stated on the package. Please enjoy it within the period.
- After opening, it’s best to use it up soon to prevent drying out and absorbing odors.
Frozen Noodle Type
- Store frozen. Convenient for buying ahead and stocking up.
- Cook them still frozen in plenty of boiling water (or in the microwave per the product instructions).
- Avoid refreezing once thawed, as the flavor declines.
Can You Freeze Fresh Noodles?
If you can’t finish fresh noodles right away, switching to freezing is one option. Wrap each single serving in plastic wrap, place it in a storage bag, press out the air, and freeze. When using, just boil them straight from frozen (this is a general home guideline; if the product labeling states whether freezing is acceptable, follow that).
How to Think About Shelf Life
The shelf life (best-before date) is a guideline for how long it stays delicious. Because rice-flour udon doesn’t rely on additives, it’s reassuring to finish it within the stated period. If you want to keep plenty on hand, using long-lasting frozen noodles or a monthly subscription lets you keep the deliciousness without waste.
To Finish Every Bowl Deliciously
Just as important as storage is how you boil it. Cook in plenty of water for the time on the package, and when serving cold, chill in cold water to bring out the bite and smoothness.
