Freeze the watermelon cubes.
Spread cubed watermelon in a single layer on a baking sheet lined with parchment. Freeze until completely solid, at least 3 to 4 hours. This ensures the slushie blends thick and frosty without needing ice.
TIPFreeze extra cubes in a zip-top bag so you can whip up a slushie anytime. - mix · ~2 min
Blend watermelon and lime juice until slushy.
1.Add the frozen watermelon cubes and fresh lime juice to a high-speed blender.2.Pulse a few times to break up the chunks, then blend on high.3.Stop and scrape down the sides with a spatula as needed.4.Blend until the mixture is smooth, thick, and uniformly frosty with no visible chunks.TIPIf the blender struggles, add 1 to 2 tablespoons of cold water — just enough to get things moving. - serve
Pour into glasses and serve immediately.
Divide the slushie between two chilled glasses. The texture is best right after blending — frosty, airy, and spoonable. Serve with a straw or a spoon while it's still thick and icy.
TIPChill the glasses in the freezer for 5 minutes before pouring for an extra-frosty presentation.
