Tender orchard fruits baked beneath a golden, crisp butter and oat crumble, served warm with velvety Madagascan vanilla custard or double cream.
Boil sugar, water, cream of tartar, bruised ginger, and cinnamon stick for 10 minutes; stir in lemon juice and chill in the freezer overnight until ice-cold.
Sift flour, baking powder, and salt; rub in cold butter with fingertips until crumbly; mix in beaten egg and milk to form a soft, elastic dough; knead for 5 minutes, wrap in clingfilm and rest for 1 hour.
Roll dough on a lightly floured surface to 5mm thickness; cut into strips 7cm long and 1cm wide; make two lengthwise slits in each strip (leaving top attached) and plait the three strands together, pinching ends firmly to seal.
Heat vegetable oil to 180°C; fry plaited dough in small batches for 3-4 minutes until deep golden brown and crisp on both sides.
Immediately drop the boiling hot fried koeksisters directly into the ice-cold syrup (keep syrup bowl over an ice bath) so they drink in the syrup with a hiss; leave submersed for 1 minute.
Drain on a wire rack; serve cold with a crisp, crunchy exterior that gushes sweet syrup with every bite.
