Place raspberries and sugar in a mixing glass and muddle until the sugar dissolves and juices release, about 30 seconds.
3 oz fresh raspberries
Spirits & Bubbles
Add vodka and Chambord to the muddled fruit, fill with ice, and stir gently for 10 seconds.
1 tsp granulated sugar
Strain the mixture into a chilled champagne flute, pressing through a fine mesh to capture all color.
Top with chilled Champagne or sparkling wine and garnish with fresh raspberries or a rosemary sprig.
2 oz vodka
Notes
During my first test, muddling frozen raspberries without thawing led to a watery mix, so I now thaw them for 30 minutes. On round two, shaking the mixture instead of stirring caused too much foam, so a gentle stir preserves the fizz. I prepped the raspberry-spirit blend 2 hours ahead and refrigerated; a quick stir before straining brought back its vibrant color.
