In a large heavy pot, heat the ground almonds, sugar, water and orange flower water. Stir with a wooden spoon until the mixture no longer sticks to the bottom and sides of the pan, 5 to 8 minutes. Let cool slightly, then wetting your fingers with ornage flower water, take tablespoonfuls and shape the biscuits to form small pears about 1 1/2 inches high.
Sprinkle the biscuits with confectioners' sugar until they are completely covered.
Note: Keepr the mixture covered while you work because it dries out quickly.
