sweetener of choice
Whisk to combine and warm over medium heat. Heat until hot to the touch but not boiling – about 4 minutes – whisking frequently.
Turn off heat and taste to adjust flavor. Add more sweetener to taste or more turmeric or ginger for intense spice + flavor.
Serve immediately, dividing between two glasses and leaving the cinnamon stick behind. Best when fresh, though leftovers can be stored covered in the refrigerator for 2-3 days. Reheat on the stovetop or microwave until hot.
