Allow to cool in the tin and then turn out onto a clean cloth.
Re-grease the tin lightly with a little butter. Make up the jelly
according to the instructions on the pack and when cold pour into
the tin. Leave in the refrigerator to set.
Whip cream with the vanilla and a sprinkle of sugar to taste. Spread
the cream over the set jelly. Place the sponge on the top (the sponge
will have shrunk slightly) and press lightly. Put the tin back into
the refrigerator for a couple of hours.
Turn the slice tin over onto a large flat surface. Heat a wet teatowel
in the microwave and place the towel on the bottom of the tin. This
will help the jelly to release.
Trim the sides. Cut into squares and serve with a pot of love
