Persephone

This aphrodisiac-laden mocktail comes from NYC's Museum of Sex and is a perfect way to set the mood on Valentine's Day. The recipe makes enough mango elixir and lavender crystals for eight drinks; if you're making only two, refrigerate the remaining elixir and store the crystals in an airtight container at room temperature (both will last up to two weeks). If you can't find dried lavender, just skip the lavender-crystal rim—it's purely optional.

To make the Persephone alcoholic, add two ounces of vodka to each drink.
