Grapefruit Rosemary Gin Fizz

Use your favorite gin, pamplemousse liqueur and Grand Marnier for a tart fizzy treat.

It is citrus season and what could pair better with your Friday cocktail hour than grapefruit and rosemary with… anything!

This week I made a fantastic cocktail throwing in freshly squeezed grapefruit and lime juice, Grand Marnier, Pamplemousse liqueur, gin and rosemary infused simple syrup. Shake it up in a cocktail shaker with tons of crushed iced. Top it off with sparkling water- tonic, , LaCriox, Pellegrino, whatever- it’ll be delicious.


Its sweet and tart.
