Blend everything on high speed until the mixture is smooth and slushy, with tiny ice shards still visible for texture.
Stop the blender and assess the texture; if it’s too thick, add a splash of juice or water and blend briefly to loosen.
Taste the slushie and adjust sweetness or tartness if needed — add more syrup or lemon juice and blend again briefly.
Pour the chilled cherry slushie into glasses, letting the vibrant red pulp swirl visibly through the icy mixture.
Garnish with a fresh cherry or a sprig of mint if desired for an appealing presentation.
