Wrap 6 cups with food grade acetate and seal with selotape, you make need to make two small snips to allow for the handle so you can slide the acetate half-way down the cup.
To make the sabayon, beat the whipping cream until it forms soft peaks and reserve in the fridge.
Place the gelatine in a bowl of cold water and leave to soften.
Heat the water to 95 degrees Celsius and infuse the coffee in a small cafetiere for 10 minutes, then strain into a mug or bowl and set aside.
Combine the eggs and sugar in a bowl and whisk until pale and thick. Add the coffee and place over a bain marie, whisk until thick and creamy.
Take the gelatine and squeeze out all of the excess water, add it to the egg mixture and whisk again until cool.
For the Italian meringue, heat together the sugar and water in a saucepan until it reaches 118 degrees Celsius. Meanwhile, whisk the egg whites in a very clean, dry bowl until they start to form soft peaks.
Gradually pour the cooked sugar syrup onto the eggs whites, whisking continuously until the meringue is cool, smooth and glossy
Gently mix the Italian meringue with the sabayon until evenly combined with no visible white lumps of meringue. Then fold through the whipped cream.
Divide evenly between the cups and fill to the top of the acetate, smooth the tops with a palette knife. Transfer to the freezer and leave to set for at least 2 hours.
To serve, whip the remaining cream to soft peak stage and remove the acetate from the cup, pipe whipped cream on top in a dome (so that it looks like coffee foam) dust with cocoa powder and garnish with chocolate coffee beans.
Place in the fridge so the cream sets and leave them to thaw in the fridge for at least 30 mins before serving.
