This "Martini" would be more accurately named a Wasabi Vodka Sour, but besides the now-dated name, this child of the early noughties is balanced with attractive...
Approached this with some trepidation, but it's great! The wasabi is the main event, spicy and almost salty, but nicely balanced by the lemon juice.
