In a large, heavy-bottomed pot or Dutch oven, combine the apple cider, orange juice, and water. Make sure the pot has a few inches of space at the top to prevent sloshing while it simmers.
8 cups apple cider, 4 cups orange juice, 2 cups water
Stir in the honey or brown sugar and the vanilla extract. The sweetener does not need to fully dissolve yet; it will melt as the wassail heats. Starting with 1/4 cup lets you adjust the sweetness later.
1/4 cup honey or brown sugar, 1 teaspoon vanilla extract
Slice the oranges and lemon into rounds, removing any large seeds. Stud several orange slices with whole cloves by poking them through the peel. Add all of the citrus slices to the pot.
2 oranges, 1 lemon, 10-12 whole cloves
Add the cinnamon sticks, remaining whole cloves, allspice berries, nutmeg, and star anise (if using). Stir gently. For a milder spice flavor, start with fewer cloves and allspice berries; you can add more later.
4 cinnamon sticks, 10-12 whole cloves, 4 whole allspice berries, 1/4 teaspoon nutmeg, 2-3 star anise pods
Set the pot over medium heat and warm until the mixture just reaches a gentle simmer with small bubbles around the edges. Reduce the heat to low to avoid a hard boil, which can make the citrus bitter and the spices harsh.
Let the wassail simmer uncovered on low heat for 30–45 minutes, stirring occasionally, until it smells richly spiced and the color has deepened. If it reduces more than you like, add a splash of water or extra cider.
Carefully taste a spoonful. If you prefer a sweeter drink, stir in additional honey or brown sugar a tablespoon at a time until it suits your taste. For a stronger spice flavor, add another cinnamon stick or a few more cloves and simmer for 10–15 minutes longer.
1/4 cup honey or brown sugar, 4 cinnamon sticks, 10-12 whole cloves
For casual serving, leave the citrus slices and spices in the pot. For a smoother party presentation, strain the wassail through a fine-mesh strainer into a heatproof serving pot or slow cooker, then add a few fresh orange slices and a cinnamon stick for appearance. Keep warm on the lowest setting.
2 oranges, 4 cinnamon sticks
Ladle the hot wassail into heatproof mugs. Garnish each serving with a cinnamon stick, an orange slice or twist, and a few cranberries if desired. For an alcoholic version, let adults add a splash of dark rum, bourbon, or brandy directly to their mug.
