Sift the flour, castor sugar, baking powder, nutmeg and salt together. Rub butter into flour mixture. Whisk egg yolks and water, add to flour mixture. Mix well to form a stiff dough, knead it and let it rest for 10 minutes.

Roll out the dough (approximately 5 mm thick) on a floured surface and cut into rounds with a pastry cutter. Line greased patty tins with the rounds of pastry.

Whisk egg whites. Gradually add sugar while beating. Fold in the coconut and mix well.

Place a little apricot jam in the centre of each of the rounds of pastry. Spoon the coconut mixture into each tartlet. Bake in the oven at 180°C for about 20 to 25 minutes until the pastry is lightly golden.

Cool slightly in the patty tin, remove and cool completely on a wire rack.

Hertzoggies are named after General Hertzog, who was South Africa’s Prime Minister between 1924 and 1939. Hertzog’s political supporters loved Hertzoggies.
