Aunt Nettie's Orange-Nut Cake

Heat the oven to 350 degrees F.

Combine the orange and raisins in a food processor; pulse until the mixture is finely ground. Pour hot water over the mixture; set aside.

Combine the flour, baking soda and salt in a medium bowl; set aside.

Combine the sugar and butter in a large bowl; beat with an electric mixer until light and fluffy. Add the eggs, one at a time, mixing well after each addition. Alternately add the flour mixture and buttermilk to the sugar-butter mixture, beating until smooth with each addition. Stir in the reserved orange-raisin mixture and the nuts. Pour batter into a greased and floured 12-cup Bundt pan.

Bake until a toothpick inserted in the center comes out clean, 40-50 minutes.

Let cake cool in pan 10 minutes. Invert it onto a wire rack; cool completely. Dust with confectioners' sugar.
