For The Topping
1 Preheat oven to 130ºC. In a large bowl whisk egg whites, vinegar and salt until soft peaks form. Add caster sugar two tbsp at a time, beating well until it is all dissolved before adding any more.
2 Heat the chocolate in a heatproof bowl over a pot of boiling water, stir until melted, remove and allow to cool slightly.
3 Spoon 12 dollops of meringue mixture onto a lined baking tray.
4 Swirl teaspoonfuls of melted chocolate through the meringue mixture.
5 Place chopped coffee beans on a lined baking tray and spread over remaining melted chocolate, allow to set, then chop roughly.
6 Place meringues in the oven and bake for 1 hour, switch off oven and allow oven to cool completely before removing meringues. Remove and place on a cooling rack.
7 Stir the cream, caster sugar and vanilla together, spoon cream onto eight of the discs, sprinkle over berries and some of the chopped chocolate-covered beans. Assemble stacks and top with remaining discs.
