For coconut rice pudding:
Add water and coconut milk in a small pot.
Rinse rice and add it into the pot.
Let it boil for 5 minutes.
Add lemon zest and sweetener.
Remove from heat and cover with a lid.
Let the rice absorb all liquid. It is preferably served cold.
For topping:
Add chopped pineapple, berries, water, sweetener, cinnamon and ginger into a medium pan.
Add cornstarch and mix well.
Cook for 5 minutes over medium heat, while stirring continuously.
Cover with a lid and remove from heat.
When both topping and pudding have cooled a bit, you can serve them. The pudding is best served cold so you may want to put them in the fridge for at least 30 minutes before serving.
