Have I ever told you I’m nuts about Rhubarb? Ever since I was little – we kids used to take the old blue Melamine sugar bowl (this is before we got the Corelle) and sit in the shade of our honeysuckle hedge and pull rhubarb, dip it in the sugar and take a bite. And repeat. Sweet & tart. Just like this Sour Cream Rhubarb Coffee Cake.
