This was incredibly easy to do and made a good drink for both the kids and adults.
Hot Mulled Cranberry-Apple Cider
3 1/2 cups apple cider
2 1/2 cups cranberry juice cocktail
2 (3-inch) cinnamon sticks
1 teaspoon whole allspice
6 whole cloves
1 (1/4-inch) piece peeled fresh ginger, thinly sliced
Carefully remove the rind from lemon and orange using a vegetable peeler, making sure to avoid the white pith just beneath the rind. Cut citrus rind into 1- x 1/4-inch-thick strips. Combine the rind strips, cider, and remaining ingredients in a crock pot and set to low for 4 hours. Strain the mixture through a sieve over a bowl, discarding solids. You can keep the cider in the crockpot on low or warm throughout the party.
