Mix all the ingredients together in a pan and bring to a simmer whilst whisking (We did this in pan on a hob the robot cook to demonstrate its cooking ability, but it can be done fine with a standard)
Simmer the mixture for 3 minutes then pour the liquid out into a container to set.
Once set blend the Coconut Gel to a smooth, silky puree.
Place the puree in a cream whipper and charge with nitrous oxide.
Dispense the finished mousse from the whipper when ready to serve.
We served this with cherry puree, dark chocolate and freeze dried cherry.
