Instructions
Mix your jelly and gelatine with half a pint of boiling water until all of the crystals have dissolved.
Pour two thirds of your mixture into a Tupperware container and put it in the fridge to begin setting (this took about 15 minutes for me).
Mix the rest of the jelly mix with the Muller Light.
When the jelly mix in the fridge has begun to set, pour the Muller Light mix on top and put it back in the fridge to set.
Remove it from the fridge and cut it into squares. Enjoy!
