Lovage is very underrated. It can be used in cooking as a replacement for celery - one of the dirty dozen veggies for pesticides. It has a strong flavor and is not pleasant raw. The leaves taste like celery and you can add a small handful to soups, stews, vinaigrettes and salads. A small amount heightens the flavour in recipes allowing you to use less salt in the dish. If you are new to this herb start off by using a tablespoon or so and see if you like it. In soup and stew making I use a whole cup of the young leaves and stems and I do not find it too strong. I also add minced lovage to omelets, salads and even vinaigrettes.
Lovage also freezes well. Chop it up and freeze in a container or bag. Proper freezing techniques would tell you to blanch in boiling water and then freeze. Blanching removes surface bacteria and enzymes which can cause flavour changes during freezing.
