Preheat oven to 120 °C fan-forced and line a baking tray with baking paper.
Whisk egg whites until soft peaks form, then gradually add caster sugar, whisking until stiff, glossy peaks form. Gently fold in flour and vinegar.
Spoon 6 oval-shaped meringues onto the tray, making a shallow indent in the centre of each for filling. Bake for 1 hour, then turn off oven and leave pavlovas inside, door closed, to rest for 1 hour.
Prepare chocolate shards by melting the chocolate, spreading thinly on baking tray with baking paper, cooling, and breaking into irregular pieces.
Carefully lift cooled pavlovas onto serving plates. Fill centres with whipped cream, top with fresh cherries and a drizzle of cherry compote.
Add a generous scoop of Connoisseur Black Forest ice cream on each pavlova, some more cherry compote, garnish with chocolate shards, and lightly dust with cocoa powder.
