There is a tradition at my brothers house of serving lemon drop cocktails for any reason, I am sure that he being a liqueur distributor and his wife being of Russian decent have nothing to do with it? Anyway they are very good and its hard to count how many you have had.
Olga's Lemon drop cocktail
fresh squeezed lemon juice
simple syrup (50% sugar/50%water dissolved)
good quality vodka (try lemon flavored)
