I made up a delicious drink yesterday. The ingredients are plain seltzer water, raspberry syrup and frozen mangoes, in whatever quantities you desire. You can also use any type of fruit syrup for the Italian soda base and any type of frozen fruit for the ice cubes.
Basically you make an Italian soda by combining seltzer and syrup. Then use some frozen fruit for ice cube substitutes. You can pour some more syrup directly on the fruit for an interesting flavor. As you drink your Bloody Sunset, the seltzer will partly melt the fruit, making it edible by the time your Bloody Sunset has sunk to the bottom of the glass.
It looks kind of like blood and is therefore favored by silly vampires who are sick of drinking things at 98.6.
