I have long been a fan of the Vesper martini, using the recipe published in the Vesper app by Q Branch:
3 oz Tanqueray Ten
1 oz Belvedere or Stolichnaya
.5 oz Lillet Blanc
Belvedere was my vodka of choice.
At my father-in-law’s house, I found myself elected to make martinis. Now, my wife’s dad favors vodka martinis, which I’ve never had success with. His vodka is Chopin, a Polish potato-based vodka.
