Basil is a delicate herb that can quickly turn brown when stored in the refrigerator. To help keep basil fresh and prevent it from browning, follow these tips:
Store it properly: Place the basil in a container or a plastic bag with a slightly damp paper towel. The moisture will create a humid environment, which can help keep the leaves fresh. Avoid packing the basil too tightly, as this can crush the leaves and accelerate browning.
Remove excess air: If you're using a plastic bag, try to remove as much air as possible before sealing it. Excess air can lead to moisture loss and increase the chance of browning.
Store at the right temperature: Basil is sensitive to cold temperatures, so it's essential to store it at the proper temperature. The ideal temperature for basil storage is around 50°F to 55°F (10°C to 13°C). Most refrigerators are colder than this, so try to find a slightly warmer spot in your fridge or use the crisper drawer, which often has slightly higher humidity and a milder temperature.
Use the refrigerator's humidity control: Some refrigerators have humidity control settings, usually found in the crisper drawers. If available, set the humidity control to a higher level to create a more suitable environment for the basil.
Trim the stems: Before storing basil in the refrigerator, trim the ends of the stems. This step can help the herb absorb water more efficiently and stay hydrated longer.
Avoid washing before storage: Washing basil before storage can introduce excess moisture, which may accelerate browning. It's best to wash the basil just before using it.
Use it quickly: Even with proper storage, basil is best when used fresh. Try to use the basil within a few days of purchase or harvest for the best flavor and appearance.
By following these tips, you can help prolong the freshness of basil and reduce the chances of it turning brown while stored in the refrigerator. Remember that basil is at its peak flavor and quality when used shortly after harvesting, so consider growing a small basil plant at home if you frequently use this herb in your dishes.
