Chocolate Raisin Bars
Preheat oven to 350℉ (180℃).
Sift all-purpose flour, salt, potato flour and vanilla sugar into a medium-size bowl.
Cut in butter until mixture forms coarse crumbs; mix in raisins.
Mix together to form a soft dough.
Roll out dough on a floured surface to a rectangle slightly smaller than an 11x7 inch baking pan.
Place rolled-out dough in pan; press to fit.
Smooth top; prick well.
Bake about 25 minutes or until very lightly browned.
Cool a few minutes. Using a sharp knife, mark through surface of mixture with lines to use as a guide for cutting.
Let cool in pan.
Cut mixture in 20 squares; remove from pan.
Place chocolate in a small bowl over a pan of gently simmering water; stir until melted and smooth.
Line a baking sheet with foil.
Dip bars in chocolate, coating evenly; lift out with a fork and tap gently on side of bowl to remove excess chocolate.
Place on foil. Place baking sheet in a cool place until chocolate sets.
If desired, any remaining chocolate can be piped over bars for decoration.
