Yes, wrapping coriander in a slightly damp paper towel and storing it in a plastic bag in the refrigerator can significantly extend its shelf life by maintaining humidity and preventing it from drying out.
Coriander, like many fresh herbs, wilts quickly due to moisture loss. The paper towel method works by providing a humid environment that slows down this process. Here's a step-by-step guide:
Wash the Coriander: Gently wash the coriander under cool running water to remove any dirt or debris. Be careful not to bruise the leaves.
Dry Thoroughly: Pat the coriander dry with paper towels. Removing excess moisture is crucial to prevent mold growth.
Wrap in Paper Towel: Lightly dampen a paper towel (it should be moist, not soaking wet). Wrap the coriander loosely in the damp paper towel.
Store in a Plastic Bag: Place the wrapped coriander in a loosely sealed plastic bag or container. This helps maintain the humidity.
Refrigerate: Store the bag in the refrigerator, ideally in a crisper drawer. The crisper drawer usually has a higher humidity level, which is beneficial.
Check Periodically: Check the coriander every few days. If the paper towel dries out, re-dampen it. Remove any wilted or yellowing leaves to prevent them from affecting the rest of the bunch.
Don't wash the coriander until you're ready to store it. Washing it beforehand and then storing it wet can actually promote spoilage. Only wash it right before wrapping it in the damp paper towel.
