I've only used parsley root in soups & stews.When I saw your post, though, it got me wondering about other possible uses. I found a site that described parsley root -- what it is, when it grows, etc.
Their recipe suggestion was "root beer float."
Doesn't answer your question, but it IS good for a chuckle.
re: almond tree
I found a recipe for roasting them like "french fries" that looks delicious - waiting for my market to get them in again. I've used them in a beef braise and in chicken soup - and don't discard the leaves. The stems freeze well too.
For a "root beer float" I suggest a basket of fries, a bottle of beer, and a hot tub. :D
Here's the link to the "fries" recipe http://mynewroots.org/site/2012/01/pa...
