Mix the water with heavy cream at room temperature.
Add chia flour, salt and sweetener. Using a whisk mix well until you get a smooth texture. Leave the pudding on room temperature for 12 minutes to allow chia to thicken it.
Sprinkle with cinnamon (or any topping of your choice) and serve. If you would like to have it cold, you can leave the pudding in the freezer for 10 minutes before serving.
