Place the syrup and water in a pot on a medium heat
In a seperate bowl add ice water and gelatine leaves and leave aside for 10 minutes to soak
Once the gelatine leaves are soft, add it into the heated syrup mixture and whisk well to dissolve
Divide the mixture into two ( one part will be used for the ravioli and one part will be used in the espuma)
Add it into the espuma machine and leave in the fridge to cool down
When ready to use it on the mocktail, insert the gas into it ( you would need three gas fillers) and pipe onto the mocktail
