Pour the jelly crystals/ powder into a jug and add the boiling water. Stir to dissolve then add the cold water. Set aside for 5 minutes.
Chop up the strawberries into small chunks and set aside.
Pour the Greek yogurt into the mixing bowl of a stand mixer or into a large mixing bowl if you are using a hand held mixer. Whisk the yogurt on a medium speed for 2 - 3 minutes then start to add the jelly mixture in a steady stream whilst continuing to whisk on a medium - high speed. Continue to whisk for a further 5 - 10 minutes until the mixture has increased in volume and is light and bubbly.
Very carefully fold most of the chopped strawberries and most of the marshmallows into the yogurt / jelly mixture. Gently spoon into 6 glasses and refrigerate for a couple of hours before serving.
Before serving decorate with a couple of the left over marshmallows and a few bits of strawberry.
