To say this nameless cocktail is "spirit-led" is an understatement but, as with a Martini, achieve a sufficiently cold serving temperature and you'll enjoy...
This is a very pleasant drink. The Cointreau does a nice job of taking the edge off the Vodka. I didn't have an orange to zest so I added a drop of orange bitters but for me this was not an improvement. Might try this again with orange flavored Vodka.
