One night in Rome, I had the most amazing drink. It had cucumber and sugar, some unidentifiable alcohol (gin? Vodka?), and I believe mint. The menu identified it as tzaziki, but I've been unable to find it online, probably because of the eponymous sauce. Has anyone heard of the drink? Could you identify the mystery liquor?
From your description it sounds like it could be a cucumber martini or a variation of one, which does use vodka.
Here's a recipe from Recipes 4 Living :
- 3 oz. Cucumber Vodka
- 1/4 oz. Lime Juice
- 2 slices Cucumber
- 3 pieces Mint
- 1/2 oz. Simple Syrup
Muddle mint and a cucumber slice in a cocktail shaker. Add other ingredients and ice. Shake and strain into a chilled martini glass, and garnish with a slice of cucumber and a fresh mint sprig.
You can use this as a starting point and tweak it to your liking or, alternatively, search for other cucumber martini recipes on the Internet. There are many available.
Just a guess, too, but I've at least seen a drink that could be the one you're looking for: "Munich Mule", a variation on the "Moscow Mule" (http://en.wikipedia.org/wiki/Moscow_mule) where you just exchange the lime for strips of cucumber. I only found recipes in German - obviously invented in Munich, saw it in Berlin once - here is a translation from http://www.rezeptewiki.org/wiki/Munich_Mule:
- 4 cl Vodka
- 5 Strips of Cucumber
- Ginger Beer
- crushed ice
Put the cucumber into a highball glass, add the Vodka. Stir, add the ice and fill with Ginger Beer. Serve immediately.
There also seem to be recipes around that recommend Tonic Water, but I've never seen Mint mentioned.
This is total hypothetical:
Mix 2.5:2.5:1 parts [Cucumber-infused Vodka]:[Whipped Cream Vodka]:Vermouth. Rub lemon rind around rim of chilled martini glass, pour, garnish, grate ginger over top. Enjoy?
