these are my current obsession! just some fresh squeezed juice topped with Pellegrino and garnished with a mint leaf. It can be just one orange, lemon, grapefruit, etc squeezed -- nothing fancy! You can also use pineapple juice or any juice really! one of my favorite cocktails used to be fresh grapefruit, mint, vodka, and then topped with pellegrino and can vouch both ways are delicious :-)
