I bought an entire bag full of gorgeous blush colored plums recently at our local street market in Deruta intending to make jam. In Italy it is frowned upon to actually grab the fruit to check how ripe it is so it wasn’t until I got home that I realized they were not ripe enough for jam. They were in fact quite firm, very tart, and quite delicious for eating, but certainly not great for jam. Since I had so many though I really wanted to use some of them for something other than snacking, so I decided to chop some up, mix them with a little jam as a sweetener, and use them in a rustic crostata. The results were a hit with all the Italian workmen who have come through our house recently and even my husband stated he preferred it to my usual basic jam crostata.
Strangely enough though, the chopped tart plums with the sweet jam combination when baked, ended up tasting almost exactly as rhubarb does when baked in a pie. I will give instructions for making the crostata exactly as I did using tart plums, but if you are using sweet dark plums, you probably will not need as much, if any of the jam. Use enough plums to completely cover the bottom crust by about 1 inch. The basic rustic cornmeal crust was adapted from a David Lebowitz recipe for Easy Jam Tart and is now my very favorite crust for any type of crostata I make. Although David chills his dough, I find it isn’t necessary, and I love just being able the press the dough mixture into the pan without having to chill and roll it.
