How to store fresh herbs
Storing fresh herbs is a battle against the inevitable, but here are a few tips for keeping them alive in time for you to eat them up:
1 Set a bushy herb like parsley, cilantro, chervil, or mint in a shallow glass of water and keep it on the counter or in the refrigerator for several days, just like a bouquet.
2 Or, rinse it, wrap it loosely in a paper or dish towel while still damp, and place it (with or without a plastic bag covering) in the crisper or at the bottom of the fridge.
3 Sturdy herbs such as rosemary or thyme can be stored in paper or loose plastic (either keep it loose or puncture some air holes to let out moisture). Or you can simply hang them upside down in the kitchen, where they will dry slowly.
4 Do not manhandle delicate herbs like chives, tarragon or basil. Rinse lightly, wrap loosely in paper and place in a plastic bag in the crisper.
5 Fresh herbs should last about a week if stored properly. If you're at the end of your garden's season and you have a tons of herbs left unused, you can most herbs to have later in the year. Kalyn's Kitchen breaks down the best way to freeze basil, rosemary and thyme.
