Just before serving, take the framboisiers out of the fridge and transfer, with the ring still in place, to the serving dishes. Slip a knife blade around the edge to loosen the dessert.
Gently lift off the ring, then pour a little raspberry coulis around the base and decorate with a small sprig of mint.
Serve fairly rapidly.
Remarks
This recipe can easily be adapted in many ways: different cake, cream or even other fruit. Let your imagination guide you...
The kirsch syrup used to soak the cake can be replaced by raspberry eau de vie, though you should leave this out if the dessert is for children.
