In a large bowl, mix together 2 tablespoons of water, the cognac and one teaspoon seedless raspberry jam.
Dip the lady fingers into this mixture and place them in the bottom of 2 tumblers. You may need to break the lady fingers in half to fit the bottom of the glasses.
Chocolate mousse: Melt the chocolate in a bowl over a saucepan of hot water. Separate the eggs and add the 2 yolks to the melted chocolate. In a separate bowl, whisk the egg whites until they form stiff peaks. Carefully fold the egg whites into the chocolate mixture a little at a time until completely incorporated.
Lay some raspberries on top of the moistened lady fingers then carefully spoon the chocolate mousse over them. Finish with a final layer of raspberries. Place in the fridge for a couple of hours or, better still, overnight.
Add custard on top, ideally home-made and warm.
Take your time as the preparation is as enjoyable as the testing!
