Ingredients

• 100 g (3.5 oz) of dark chocolate (over 70%)
• 100 g (7 tbsp) of butter

• 50 g (1/3 cup) of flour
• 3 eggs
• An untreated orange

Preparation

Step 1

Melt butter and chocolate in a medium heat-proof bowl over a saucepan of simmering water.
Remove from heat, add sugar and stir with a wooden spoon or with a normal one, but not with a whisk, you do not want to incorporate air. Stir until sugar dissolves.

Add flour, stir and add the eggs 1 by 1 stirring after each addition.

Grate an orange into the chocolate mixture.

Place in moulds or ramekins. Bake in the oven 10 to 12 minutes.
