Pour the chilled rosé into your blender and add the citrus zest and honey or syrup.
Add the crushed ice to the blender, filling it up to the top for a thick, icy texture.
Seal the blender and blend on high speed until the mixture is smooth and slushy, about 30-45 seconds. You should see a vibrant pink color with a frosty appearance and gentle bubbling sound.
Stop the blender and check the texture; if it’s too thick, add a splash more rosé and pulse briefly to incorporate.
Pour the slushie into glasses, letting the frosty mixture cascade in a swirl of pink bubbles and ice particles.
Garnish with extra citrus zest or a slice of citrus fruit for an extra pop of color and aroma.
Serve immediately with a straw or small spoon, enjoying the chilled, tangy, fruity frozen delight.
