There's a thimble-sized Farmer's Market in our neighborhood and one August visit, I bought a fresh plum cake. I thought nothing of it except "Well, now I have dessert for tonight." Little did I know what an adventure it would turn into! The wrapping from the bakery was tossed and unobtainable after my family went insane for this cake! Beyond moist, a perfect blend of tart and sweet, I spent days trying to locate a similar recipe with no luck; every "plum cake" that I found had either plum baby food or some crumb or streusal topping. I finally located the bakery through the Farmer's Market and found out the name of the cake. It's a Polish delicacy and MUST be made with fresh plums, in season fruit.
