*I used half a 135-gram pack of jelly cubes (in the UK). I've attempted to adapt the recipe Australia (I understand jelly crystals is sold as powder/gelatin mix, not cubes as in the UK). I'm pretty sure this will work just as well using the jell-o powder, but please let me know if it doesn't and we'll think again!
You can play with the amounts of cream and yogurt, so long as you use about 300ml / 1¼ cups altogether.
Don’t like too much of a yogurty flavour? Just replace some of it with more cream!
Of course, you can also experiment with different jelly flavors. How about strawberry, lemon, or passion fruit?
