I have a little cookbook I bought at an herb garden and one of the recipes I always wanted to try was for potato salad with lovage (the book is packed away in storage or I'd share the info from it). I tried googling a recipe for this just to see what I could find and I came across this article on lovage ... pretty good (with recipes, including "Warm Potato Salad With Lovage") and then I looked at the author - it's Michael Wieshan ... I think he used to do Victory Garden? Anyway, lots of good info on lovage!
