Defrost in the packaging in the fridge for 12 to 14 hours, or at room temperature for 2 hours.
Remove outer film and carefully place the cheesecake, still in its ring, onto a cold plate.
Using a knife or small spatula loosen the cheesecake from the ring by sliding the knife inside the ring around the cheesecake. Carefully open and remove the ring. Serve with your favourite accompaniment.
If you prefer, you can serve this when it is still slightly frozen, for a delicious 'semifreddo' effect.
Serving suggestions: serve cold with fresh berries, ice cream or sorbet, pouring cream & fresh mint leaves.
