Squeeze the juice from the oranges, put it in a plate, then quickly soak the biscuits in it on both sides and arrange it on the bottom of the baking tin (the size of the baking tin used is 31x22 cm) to cover it completely.
Then spread half of the cream evenly over the biscuits. Arrange a layer of soaked biscuits on it and coat with the remaining cream.Place the prepared in the refrigerator for at least 2 hours to cool well, then sprinkle with grated white chocolate before serving.
