A great SF restaurant, Ponzu, has a new drink that has gotten a lot of buzz around town and has now been written up. The Sultana is not a raisin based drink or a tribute to the steamboat that sank in the late 1800's, but a nod to the powerful female ruler of India of centuries ago. Ponzu is not the japanese sauce, but the name of the restaurant.
It's unique taste is derived from vanilla vodka (Ponzu uses Stoli, but really, ewww) and from Yuzu juice. Yuzu is a japanese citrus fruit that you won't find here in the US but you should be able to find a bottle of the stuff. It has a lemon-lime mix characteristic and is also useful for Lemon Drops.
How to make The Sultana:
1/2 ounce yuzu juice
1/2 ounce fresh lime juice
1 ounce simple syrup
10-15 fresh mint leaves
3 ounces Stoli Vanil vodka
Place the yuzu juice, lime juice, simple syrup, and all but one of the mint leaves into an empty mixing glass and grind them with a wooden muddler. Add the vodka and enough ice to fill the glass two-thirds full. Shake for approximately 15 seconds and strain into a chilled cocktail glass. Garnish with the reserved mint leaf.Props to Gary Regan over at the SF Chronicle for chasing this one down.
