In a large saucepot combine the wine, orange juice, orange slices, cinnamon stick, and pectin. Bring those ingredients to a boil, stirring frequently. Now add the sugar and stir until it’s completely dissolved. Bring the mixture back to a rolling boil. Stir the mixture constantly while it boils (hard) for 2 minutes. If the mixture starts to boil up, blow on it! Now, remove the mixture from the heat. If any foam floats to the top, skim it off.
