1. Cut the Castello Organic Blue cheese into small pieces and mix well with the marzipan, almonds and basil.
2. Cut the apples into halves and remove the core. Cut a thin slice off the ‘round cheek’ of the apples so they stand more securely. Place the halved apples on a baking sheet lined with grease-proof paper and spread the cheese & marzipan filling on the apples’ cut side.
3. Beat the egg whites until soft peaks form. Add sugar and beat for 1-2 minutes more until stiff peaks form.
4. Spread the meringue on top of the cheese filling and bake the apples in the middle of the oven for ½ hour at 150°C. Garnish with the almond slivers and basil leaves. Serve immediately.
