Here's what you need to make one Rosemary Grapefruit Fizz cocktail:
- 2 oz gin
- 1 oz fresh grapefruit juice
- 1/2 oz simple syrup
- 2-3 sprigs of fresh rosemary
- Ice cubes
- Soda water
- Grapefruit slice and rosemary sprig for garnish
Fresh ingredients are key. Use newly squeezed grapefruit juice for the best taste. You can make simple syrup at home by mixing equal parts sugar and water.
