Sorbet: Mix pineapple juice, orange juice, grapefruit juice, lemon juice and grenadine and sweeten a little more if necessary. Pour into a shallow bowl and place in the freezer, stirring from time to time.
Ravioli: Dissolve the cocoa in water. Mix the flour, eggs, sugar and dissolved cocoa to a smooth dough, adding water if necessary. Chill the dough for about 40 minutes.
Form about 8 walnut-sized balls from the nougat. Roll out the ravioli dough thinly (dust with flour), cut out circles of approx. 8-10 cm in diameter, place one nougat ball in each and fold up.
Press the edge well together.
Heat some water in a saucepan and leave the ravioli to stand in boiling water for a few minutes, then drain.
Dresser: Arrange two pieces of ravioli and two scoops of sorbet on each plate, garnish with half a slice of pineapple and three raspberries. Spray some whipped cream and put a decorative chocolate heart in it, decorate with chocolate sauce.
