Dark chocolate mousse

Break the chocolate into small pieces. Place in a bowl and melt over barely simmering water.

Once the chocolate is fully liquid, add the coffee, and mix well. Add the butter next, stirring all the while. Ensure that there are no lumps in the mixture.

Separate the eggs and mix the yolks in with the chocolate mixture

Best the egg whites in an electric mixer until doubled in size and they form stiff peaks when the mixer is lifted. Gently add the chocolate mixture to the egg whites and mix well with a metal spoon, careful not to squash the air out.

Pour into a dish and leave in the fridge until it sets. As a finishing touch (optional), grate some leftover chocolate onto the top before you serve. Bon appetit!!
