First prepare the jelly and place it in the fridge.

Then prepare the pudding according to the instructions on the box.

Then soak the biscuits in the milk (not much, just dip them) and spread a layer of them in a slice tray. Pour the custard over them and then place the dessert in the fridge.

When the jelly starts to set (not too much) then spread it over the dessert and refridgerate until the jelly is fully set.
