This is my version of a lemon martini they serve at The Bristol Lounge at the Four Seasons in Boston.
- 1 shot Grey Goose Citron Vodka (colder is better)
- 1 shot Limoncello lemon liquer (ditto)
- 1 shot fresh-squeezed lemon juice (sometimes I add a little lime juice)
Put it all in a cocktail shaker with lots of ice, shake vigorously for 30 seconds and then pour into a chilled martini glass with or without a sugared rim (run lemon around the rim of the glass, then dip it in superfine sugar; refrigerate). Top off with Limonata sparkling lemon soda (found in the Italian foods section of many supermarkets). If Limonata is unavailable you can use simple syrup.
