Combine in a shaker with ice, shake and serve! Use some orange slices and cinnamon sticks to garnish if you want to win the hostess with the mostest award.
Note: The better your lemonade and cider, the better your drink will be! I like a very tart lemonade and a cider with a lot of spice. If you can't find a cider with a lot of spice, you can always simmer it with some spiced tea bags to make it more flavorful—it's a whole extra step, but sometimes good cider is hard to find.
