Rizogalo is Greek rice pudding flavored with the zest of lemon and orange. This pudding can be served hot or cold; for breakfast or as a dessert. If you want lemon and orange zest in the pudding, grate them instead of adding slices of the rind that would later be removed.
Whisk together the milk, cream, rice, cinnamon stick, lemon and orange rind in a pot over low heat for 3 minutes to keep the rice from sticking to the bottom. Whisk every 5 minutes after that for 30 minutes.
Mix the water and cornstarch together to make a slurry. Whisk into the rice pudding. Turn off the heat.
Remove the cinnamon stick, lemon, and orange peel. Stir in the sugar and vanilla extract.
