Flourless chocolate torte

Separate the eggs, whites into a very clean bowl and yolks into another.

Melt butter in a saucepan on low heat; chop the dark chocolate.

Add the chocolate to the melted butter and stir until melted; mix in the cocoa powder, almond flour and most of the sugar, reserving a couple of tablespoons. Let cool.

Preheat the oven. Mix in the egg yolks one at a time, then the vanilla and a tablespoon of coffee-based liquid.

Whip the egg whites with a hand mixer to stiff peaks (eight and a half minutes here).

Line the cake pan with parchment paper.

Mix a quarter of the whites vigorously into the thickened chocolate mixture to loosen it, then add the batter to the whites and fold gently from the centre outwards until even.

Pour into the cake pan and bake about an hour, until a knife poked in comes out relatively clean.
