Recipe: Open Jam Tarts

Time to bake until paste loosens from the dish. Line shallow tin dish with puff paste, put in the jam, roll out some of the paste, wet it lightly with the yolk of an egg beaten with a little milk, and a tablespoonful of powdered sugar. Cut it in narrow strips, then lay them across the tart, lay another strip around the edge, trim off outside, and bake in a quick oven.
