That sounds like a disaster. Rhubarb leaves are toxic due to the oxalate levels in them.
The stalks (with their far fewer oxalates) are used in pies, either the old Pieplant Pie or Strawberry-Rhubarb Pie.
They're very tart, like cranberries and need a fair amount of sugar to make them edible.
You are correct about the rhubarb leaves. Almost too bitter to be worked with. I’m finding out more as I look into it.
My recipe may work best just taking rhubarb and artichoke out, but I was trying to come up with a recipe that would use them. A challenge for the pondering.
