Dip the rim of each glass into the red mixture, spinning slowly to coat. Turn glasses upright; the red liquid will drip, then set. Drinkers' lips may be stained pink -- much like those of a vampire.
FOR THE "BLOOD"
- 3 tablespoons corn syrup
- 1/4 teaspoons red food coloring
FOR THE DRINK
- 20 ounces pineapple juice
- 1 can (15 ounces) cream of coconut
- 1/2 cup heavy cream
- 1 cup orange juice
- 10 ounces good-quality rum
Pour the corn syrup in a shallow bowl. Dip a toothpick into the food coloring, and stir a very small amount into the syrup to combine. Hold a glass by the stem, dip rim into the syrup mixture, and turn glass, coating entire rim. Turn the glass upright, allowing mixture to drip down sides. Dip the remaining glasses. Set aside.
Whisk together drink ingredients. Place 2 1/2 cups ice in a blender, and add 1 cup drink mixture. Blend until smooth; add more pineapple juice if mixture is too thick. Repeat with remaining ice and mixture. Carefully pour into prepared glasses; serve.
