Not just rhubarb
The shrub thing really is a sickness around these parts. I did rhubarb and strawberry just a little while ago, and now I’ve got some cherry going as well. This really is ten minutes of chopping, two minutes of stirring with the sugar, 30 seconds of glugging in the cider vinegar, and two weeks of waiting followed by an entire summer and fall of sipping on delicious things.
I’m not sure why we’re not all doing it all the time. It really is the best thing to do with all that extra fruit you find yourself with all summer long. 
If I ever get to the other coast I will visit and offer to help in the kitchen in exchange for tasting everything. (I am also a very good yarn-fondler, in case you need help with that as well.)
So long as it doesn’t devolve into yarn chewing…the kittens are protective of their jobs and wouldn’t want anyone else doing the chewing for them.
