Zézette de Sète

Instructions

1. Preheat the oven to 180°C and line a baking tray with baking paper.
2. In a bowl, whisk the egg with the sugar until pale and slightly frothy.
3. Add the oil, white wine, vanilla, orange zest and salt, then mix.
4. Fold in the sifted flour and baking powder, mixing just until you get a soft, smooth dough.
5. Shape small bars about 10 cm long and 2 cm wide, spacing them well apart on the tray.
6. Bake for 20 to 25 minutes, until golden and firm to the touch.
7. Leave to cool completely on a wire rack; they become crisp as they cool.
8. Dust with icing sugar before serving.
