A light and bubbly summer cocktail combining fresh blackberries, gin, and a rosemary-infused simple syrup for a refreshing and herbaceous twist on the classic gin fizz.
Do not over-muddle blackberries to avoid bitterness from seeds. Use freshly squeezed lemon juice for best flavor. Simmer rosemary syrup gently to prevent bitterness. Chill glassware beforehand to keep fizz lively. Add soda water last to preserve bubbles. Rosemary syrup can be stored refrigerated up to two weeks.
