Uncle Don’s Shortbread

5 oz. (5/8 cup) unsalted butter

6 oz. ( 1 ½ cup) plain flour

2 oz. (1/2 cup) rice flour, corn flour or ground rice

3 oz. (3/8 cup) powdered sugar

Put slightly more butter than given in a cloth and squeeze out to extract excess moisture, then measure or weigh for the exact amount.

Sift flour and rice flour, mix half sugar with the flours, rub in butter until like fine breadcrumbs. Add remaining sugar and knead well. Form into round. Flute edges. Prick with fine skewer.

Bake on greased baking sheet in preheated oven 300° for 40 to 50 minutes until firm and light golden. Cool for 5 minutes and then mark into 6-8 portions. Remove from tray when completely cooled.

Can be dusted with powdered sugar before serving.
