Thanks to Rob House for filming and editing this.
I'm going to try something like knotweed thyme soup soon, and also I want to try frying them. Think fried artichokes. I also ate some with peanut butter last night. Other than the fact that I gobbled up way too much peanut butter in a short amount of time, causing me to be swallowing for the next 20 minutes or so, it was pretty good. I've also been cutting up raw pieces and adding them to any hot savory dish and they work well there as little bursts of lemony crunch.
