2In a large bowl, beat the egg, then beat in brown sugar and salt. Stir in vanilla and lemon extract. Beat until light and bubbly, then stir in melted butter. Fold in raisins. Drop filling by spoonfuls into tart shells.
3Bake in preheated oven for 10 minutes. Reduce oven temperature to 350 degrees F (175 degrees C) and bake an additional 20 to 25 minutes, until filling is set and pastry is golden brown.
