A bright, crisp, and icy sangria slushie blending frozen raspberries, fresh blueberries, Prosecco, and citrus for a refreshing summer party drink.
Do not overblend to keep a slushy texture; keep Prosecco and white wine well chilled; add Prosecco after blending to preserve bubbles; adjust sweetness gradually; use frozen fruit for natural ice and texture; can prepare sangria base without Prosecco up to 24 hours ahead and add Prosecco before serving.
