- 1/2 medium orange
- 3/4 cup water
- 1/4 cup turbinado or granulated sugar
- 20 whole cloves
- 2 cinnamon sticks
- 2 whole star anise
- 1 (750-milliliter) bottle dry red wine
Rum or amaretto, for serving (optional)
Using a vegetable peeler, remove the zest from the orange in wide strips, taking care to avoid the white pith; set aside.
Juice the orange and set the juice aside.
Combine the water and sugar in a large saucepan or Instapot and boil until the sugar has completely dissolved.
Reduce the heat and add the cloves, cinnamon, star anise, orange zest, and orange juice. Simmer until a fragrant syrup forms, about 1 minute.
Reduce the heat further and add the wine. Let it barely simmer for at least 20 minutes but up to a few hours. Be sure not to let it reach a full simmer if you don't want the alcohol to burn off.
Strain and serve in small mugs, adding a shot of rum or amaretto and garnishing with the orange peel and star anise if desired.
