- Preheat the oven to 180 C / Gas 4. Grease a fluted cake tin.
- Beat eggs and sugar in a double boiler (or a metal bowl placed over a pot with simmering water, but make sure the bowl does not have contact with the water) until light and fluffy. Remove from heat.
- Gently stir in potato starch, flour and baking powder. Stir in mayonnaise and vanilla extract.
- Tip mixture into tin and bake for 50 minutes. Cool and sprinkle with icing sugar.
Potato starch vs flour
Note that potato starch is not the same as potato flour, though sometimes potato starch is erroneously labelled as potato flour. Make sure what you buy is a refined, white powder, as true potato flour is made from the entire potato, including the skin, and is less refined.
