Drain the cherries and pour into 4 ovenproof cups (250 ml). Beat the egg whites until stiff, adding sugar. Fold in flour first, then grated coconut. Spread the macaroon mixture over the cherries and bake in a preheated oven (electric range: 175°C/ convection oven: 150 °C/ gas: level 3) for approx. 20 minutes.
