Cut kiwi and 4 orange slices and place on a plate, sprinkling with 4 tablespoons of sugar to leave the juice.
Mix the juice from the sliced fruit with the juice from 2 oranges and the one from the pineapple box.
Put the gelatin soaked in 100 ml of juice.
Put a pan with boiling water.
Rub the yolks with 6 tablespoons of sugar, add the milk and boil in a steam bath, stirring constantly. After removing the cream from the heat, melt the gelatin and add it over the cream, mixing well.
Beat the whipped cream with 3 tablespoons of sugar and vanilla sugar, then add the cream and chopped pineapple and mix lightly with a spoon.
Moisten a pan, then cover the walls with foil (aluminum or plastic). Put the fruit slices around the pan, then put 2 or 3 rows (depending on the size of the pan) of cream and biscuits soaked in juice. Cover and leave in the fridge until the next day, then turn over on a plate.
