This is ideal for homemade strudels, hors dâ€™oeuvres, potato knishes, quiche, pies or tarts. It freezes like a dream and you can made a few batches in a food processor in minutes. It is a crisp, tender, buttery dough that is a bit like puff pastry but low tech. You can use yogurt to replace the sour cream but do not use low-fat sour cream (too watery). ONe of my all-time favorites doughs. Oh! Did I tell you it makes sublime rugulah?
