Ramsons (Allium ursinum) is the wild food we enjoy eating all year long. I freeze most of it. I also made pesto last year and preserved its buds in vinegar. If the weather permits I will gather more leaves and make more pesto this time. I crush leaves and add olive oil. All other ingredients are added later. If they are added at all.
I always feel a bit uncomfortable when gathering ramsons' leaves alone because I do this in the area where bears live. It was only a fox around there yesterday, barking. And I heard a cuckoo sing for the first time this year. :)
