Raspberry-Rhubarb Slab Pie

 Raspberry-Rhubarb Slab Pie
"Slab pie" is a pastry baked in a jelly-roll pan and cut in slabs like a bar cookie—or a pie bar, if you will. My grandfather was a professional baker and served pieces of slab pie to his customers back in the day. Here is my spin, featuring rhubarb and gorgeous red raspberries. —Jeanne Ambrose, Milwaukee, Wisconsin
