Yes, quinoa should be thoroughly dried after rinsing and before storing to prevent mold growth and spoilage. Drying ensures its longevity and maintains its quality.
Rinsing quinoa is essential to remove the naturally occurring saponins, which can give it a bitter taste. However, the added moisture from rinsing creates an environment conducive to mold and bacterial growth if not properly addressed. Drying the quinoa thoroughly after rinsing removes this excess moisture, significantly reducing the risk of spoilage during storage. You can dry quinoa by spreading it in a thin layer on a baking sheet lined with parchment paper and allowing it to air dry for several hours, or even overnight, until completely dry to the touch. Alternatively, you can use a low oven setting (around 170°F or 77°C) to speed up the drying process, but be sure to monitor it closely to prevent burning. Once dried, store the quinoa in an airtight container in a cool, dark, and dry place.
To test if your quinoa is dry enough for storage, try pressing a few grains between your fingers. If they feel completely dry and separate easily, it's ready. If they stick together or feel damp, continue drying.
