Prepare the peach purée: Blend ripe, peeled white peaches until smooth. For best texture, strain through a fine-mesh sieve. Chill for 30 minutes.
Pour chilled purée into a champagne flute. Slowly top with cold Prosecco.
Stir gently to combine, keeping the bubbles intact.
Garnish with a peach slice and serve immediately.
Tips:
• Use ripe white peaches for natural sweetness — no added sugar needed.
• Keep both the purée and Prosecco cold for the crispest flavor.
• Adjust sweetness to taste with more purée or a drier finish with extra Prosecco.
