Stove Top Christmas Potpourri
Ingredients
1 1/2 cups fresh cranberries
3 tangerines, halved
3 whole cinnamon sticks
2 star anise (optional, gives a strong black licorice smell)
1 teaspoon whole cloves
1 inch piece fresh ginger
1 vanilla bean + 1 tablespoon vanilla extract
1 small branch fresh pine
1 cup apple cider, pomegranate or cranberry juice
Water
Directions
Combine all the ingredients in a medium size sauce pot. Fill the pot with water until it reaches 3/4 the way full. Place the pot on the stove and bring to a gentle boil. Reduce the heat to a simmer, adding more water as needed. I let mine simmer for close to 4 hours and then let it cool overnight and simmer again the next day. Just be sure to keep adding more water.
