What is the best way to store corn silk to keep it fresh and flavorful?

Store corn silk in an airtight container—such as a glass jar with a tight‑sealing lid or a resealable plastic bag—to protect it from moisture and air. Keep the container in a cool, dry place, away from direct sunlight and strong odors, as the fibers can absorb surrounding scents. When stored properly, the herb remains fresh for up to 12 months; however, for best flavor, use it within 6 months of opening. If you notice any off smell, discoloration, or mold, discard the product. When you are ready to brew, simply measure the desired amount, add hot water, and steep as described above. If you prefer to keep a ready‑to‑brew supply, you can pre‑portion the herb into single‑serving sachets and store them in a sealed bag.
