From the files of Judy Bales: a recipe she pinched from Better Homes & Gardens many years ago. Don't know if she ever got around to making it, but it sounds so easy and yummy, I will definitely be trying it soon!
In a Dutch oven, combine peaches, 1 cup sugar, water, cornstarch, and cinnamon. Cook and stir till thickened and bubbly. Transfer to a 3-qt. rectangular baking dish.
Meanwhile, for filling, stir together brown sugar and melted butter. Add pecans; toss to coat. Set aside.
For dough, in a large mixing bowl stir together self-rising flour and the 2 tsp. sugar. Cut in shortening till mixture resembles coarse crumbs. Make a well in the center; add buttermilk. Stir just till dough clings together.
Turn dough out onto a lightly floured surface. Knead gently for 10 to 12 strokes. Roll to a 12x8-inch rectangle; spread with pecan filling. Roll up from one of the long sides. Cut into twelve 1-inch-thick slices. Place slices, cut side down, atop hot peaches.
Bake, uncovered, in a preheated 400-degree oven for 25 to 30 minutes or till biscuits are golden. Serve warm with half-and-half or light cream, if desired, or vanilla ice cream.
