I've written at length about my love of the cucumber martini. My favorite is at the Banc Cafe - they make their own cucumber vodka with Ketel One and yes, cucumbers. A kind of mascerated love juice that is so delicious.
I don't think I can maintain a supply of cucumber vodka like the Banc Cafe, and I don't get to go very often, so I'm looking for ways to introduce a cucumber martini more frequently than 2 or 3 times a year. This isn't quite it - perhaps you all have some ideas to make it better.
I made a cucumber juice to create the martini - I blended a whole english cucumber (but I recommend you peel yours) with about a half cup of water. I strained it and used it in this drink. I think next time I would puree the cucumber without the water.
3 parts Belvedere Pink Grapefruit vodka (this is what I have!)
1 part St Germain liquor
4 parts cucumber juice
juice from a wedge of lemon
Shake with all your might with ice cubes!
