If so, what did you think of her family recipe for "Sand Tarts"??
Those were "Pecan Crescents" if ever I saw any. All the "Sand Tarts" I've ever known or baked are made from sugar-cookie type dough that's rolled and cut out (or molded in a mold - I've seen those, too). There's an egg-white wash before baking and a sugar/cinnamon mixture sprinkled on top -- the "sand." No nuts in the dough, unless you press a sliver of almond on top before baking.
Her cookies were a shortbread-type dough with lots of chopped pecans. She formed the cookies into fat crescents before baking and rolled them in powdered sugar afterwards.
I've never seen a "Sand Tart" like that, have you?
