Sigrid tried this cocktail at Murray Circle, at Cavallo Point, in Sausalito (I suppose technically it was from the Farley Bar).  I don't know what they call it there, and I can't guarantee this is really exactly the same, but it's how we like it.

The chipotle vodka pulls no punches.  It's an amazing blast of fresh pepper, smoke, and spice.  The 209 is also key—once, when we were out of 209, I tried another gin, and it was a markedly different drink.  The simple syrup adds a touch of sweetness, and the ginger adds yet another spice highlight.  Don't skip the cilantro, as its flavor really complements the chipotle well.

• 1 oz Hangar One chipotle vodka*
• 2 oz 209 gin
• 1 T ginger-infused simple syrup†
• fresh cilantro

1. Muddle a few leaves of cilantro at the bottom of an old-fashioned glass.  Fill glass with ice.
   
2. Add vodka, gin and syrup to a cocktail shaker.  Shake with ice until cold. Strain into glass.

* This is a small batch, limited edition "Alchemist Series" vodka from Hangar One.  As far as I know, it actually has been two of their three batches of Alchemist Series vodkas (the other being a wasabi vodka). I suppose it's possible they will make it part of their regular production. We found our bottles (we've bought three so far) at K&L Wine Merchants.

† To make the ginger-infused simple syrup, grate an inch or two of fresh ginger, and heat in a sauce pan with 1/2 cup each of sugar and water.  Simmer for ten or so minutes, and let cool.  Strain through cheese cloth, squeezing to get all the syrup out.
