Split the sponges and sandwich together with raspberry jam. Arrange in the base of a shallow dish (about 20 cm (8”) diameter, 6 cm (21/2”) deep.
Sprinkle the sherry over the sponges and cover with fresh raspberries. Sprinkle over crushed ratafia biscuits and level gently with the back of a metal spoon.
Carefully pour over the custard. Decorate with blobs of softly whipped cream and sprinkle with flaked almonds. Serve chilled.
