1: Prepare 800 g bavaroise cream and flavour it with coffee.
2: Pour it into individual glasses or dishes. Sit these on a baking sheet with either a tea towel or sheet of paper over it to stop them slipping, and refrigerate for 2 hours. This can be done the day before. In this case, cover the dishes with plastic film.
3: Shortly before serving, prepare a sabayon with 3 egg yolks, 5 tablespoons sugar syrup and 5 tablespoons rum, following these hints.
4: Pour the sabayon into the dishes.
5: Garnish with toasted flaked almonds, placing them gently onto the sabayon, and serve right away.
Remarks
If you don't like rum, use half-and-half water and lemon juice instead.
