Great Gran's Rhubarb Crumble

We have been enjoying the amazing produce that our kitchen garden has been producing!  This time it was rhubarb that families harvested and shared.  One student said proudly, "I'm giving this to Great Gran to make her famous Rhubarb Crumble". So, after delivery off the hill and a return package a few days later, we are enjoying a delicious historical recipe, fresh from the kitchen of a very loved Great Gran.
