Since the base recipe for panna cotta produces a very light taste, the dessert is often served “dressed up” with various sauces. Adding sauces made of berries, summer fruits, or even tropical fruits can be delicious. Typically you would add these after the panna cotta has achieved the desired firmness. You could even serve panna cotta with a dollop of jam if you want to keep things simple, thus creating a dessert somewhat similar to castle pudding.
