Ever since lockdown, fresh herbs have become particularly hard to find in our area and most times, it's "luck of the draw". If I should I find any, they had to last until next time, so I decided to preserve, by drying them.
I lined a cookie sheet with parchment paper and spread them out. Put them in the oven for about 10 to 15 minutes at 325 degrees F. Once dried, they crush easily. I used a few small, recycled, glass spice jars for storage, or small (sealable) plastic bags work too.
Currently, I have a very nice assortment of home dried Basil, Parsely, Cilantro and Mint. Best of all, I never do without, when the fresh ones are sold out.
