Mousse au chocolat (8 pers.)
Shopping list: 1 tablet of pure chocolate of 200 grams, e.g. Nestlé dessert chocolate (at least 52% cocoa). 5 eggs, a cup of strong espresso, 75 grams of soft butter, 30 grams of sugar and a little salt.
Melt the chocolate au bain marie and add the coffee and then the soft butter, keeping it a bit warm after melting. Break the eggs and separate the yolks from the whites. Stir the yolks in one by one to the chocolate and add the sugar. Whisk the egg whites in a separate bowl with a little salt until you have a firm mixture. Then add the whites bit by bit to the chocolate mixture with a soft spatula. Not too quickly, otherwise it deflates. Fill the little bowls or glasses with the mousse and keep them at least 4 hours in the fridge (at most 24 hours).
