125g/4oz/1 cup + 2 tbsp self-raising (self-rising) flour
a pinch of salt
1 tbsp caster (superfine) sugar
1 medium (US large) egg, separated
25g/1oz/2 tbsp butter, melted
250ml/8fl oz/1 cup milk
maple syrup to serve
1 Heat the waffle iron according to the manufacturer’s instructions.
2 Mix the flour, salt and sugar together in a bowl. Add the egg yolk, melted butter and milk and beat until you havea smooth coating batter.
3 Whisk the egg white in a clean, grease-free bowl until stiff. Fold gently into the batter with a metal spoon. Pour just enough batter into the iron to run over the surface.
4 Close the iron and cook for 2–3 minutes, turning the iron if using a non-electric type. The waffle is cooked when it is golden brown and crisp and easily removed from the iron. Cook the remainder in the same way.
5 Serve the waffles immediately with maple syrup.
