Combine orange juice, pomegranate juice and sugar in a medium saucepan. Keep stirring at medium-high heat until sugar is melted.

Add cranberries, cinnamon stick, nutmeg, orange zest. Bring to boil, reduce heat to medium and cook for about 20 minutes, stirring from time to time.

Take 3-4 tablespoons of juice from the saucepan and combine with cornstarch, using a smaller dish. Mix until well combined, then pour into a saucepan and boil until it thickens, stirring constantly.

Don‘t let it become too thick, because it will thicken some more while cooling.

Remove from heat and let cool at a room temperature, then put in the fridge to cool completely.
