1 shot vodka
1/2 shot Creme de Cassis (only a delicious one from Dijon, of course!)
fresh mint (roughly chopped)
In stemmed glass, smoosh/mangle/manhandle/dismantle (whatever you so choose) 5-6 raspberries (per glass). Add mint, Creme de Cassis and vodka. Fill to top with Pellegrino. Enjoy with good friends.
Same recipe as above--just substitute blackberries for raspberries.
