2. Finish glaze
In a separate container, whisk together the remaining ¼ cup of wine with a teaspoon of cornstarch, then add it to the sauce pan, along with the clove, ginger, vanilla, salt, and pepper. Stir well, and turn the flame back up. Let the mixture reach a boil, then reduce the heat and let it simmer for an additional 10 minutes. Remove it from the heat to cool.
