Preheat the oven to 180°C/fan oven 160°C/Gas Mark 4.

Position an oven shelf towards the center of the oven. Use a small knob of the butter to grease two Le Creuset Stoneware Heart Ramekins.

Beat together the remaining butter and sugar, adding 1 tablespoon of hot water. Sift in the flour, then stir it in with the lemon zest and juice. Add the beaten egg yolks, milk and Amaretto liqueur to the mixture (don't worry if the mixture curdles a little).

Whisk the egg whites in a grease-free bowl until they hold their shape. Fold them into the lemon mixture, then transfer to the prepared dishes.

Stand the dishes in a roasting pan with water to come about a third of the way up their sides. Bake for 40 minutes until risen and golden.

Serve immediately, sprinkled with a little icing sugar.

Cook's Notes

If you prefer a non-alcoholic version, replace the Amaretto with 2 more tablespoons of milk.
