Texas Osgood Pie

Make Pie Crust (or have ready).

Heat oven to 350F.

Beat egg yolks in large bowl until thick and creamy, about 5 minutes. Combine sugar, flour, cinnamon, and cloves in small bowl; add to egg yolks in small additions, beating well after each. Add vinegar and vanilla; mix well. Stir in finely chopped pecans and raisins.

Beat egg whites in clean bowl with clean beaters until foamy; add salt and beat until whites are stiff but not dry. Fold whites into egg yolk-sugar mixture. Spoon filling into partially baked pie shell; smooth top with spatula. Bake pie until top is puffed and brown, 25 to 30 minutes. Remove to wire rack; let cool to room temperature. Sprinkle with ground pecans, if desired, before serving.
