1extra flour, for rolling canola or other mild vegetable oil, for cooking icing sugar or cinnamon sugar, for dusting
2In a medium bowl, stir together the cheese, sour cream, sugar and egg. Add the flour, baking powder and salt and stir until you have a thick batter. If you like, stir in some raisins or currants.
3Put some flour in a shallow bowl or pie plate. Scoop medium spoonfuls of batter and roll in flour to coat. Heat a couple inches of oil over medium-high heat until hot but not smoking – a crust of bread should sizzle if you dip it in. Gently lower a few ponchiki at a time into the oil – don’t crowd the pot – and cook until golden on the bottom. Flip and cook for a few minutes on the other side, until deep golden. Transfer with a slotted spoon to a paper towel-lined plate.
4Dust with icing sugar or cinnamon sugar while still warm.
