Add the ice cubes to the blender, creating a substantial icy base for the slushie.
Pour in the freshly squeezed lime juice, which provides the tangy citrus flavor and brightens the mixture.
Add the simple syrup or honey to sweeten the drink, balancing the tartness of the lime.
Pour in the tequila, giving the slushie its distinctive boozy kick and depth of flavor.
Secure the lid on the blender and blend on high until the mixture is smooth, with a slightly granular or icy texture that clings to the sides of the container.
Check the texture; if it’s too thick, add a splash of water or additional lime juice and blend briefly again.
Pour the frozen margarita slushie into chilled glasses, allowing the icy mixture to cascade over the rim for a refreshing presentation.
Optional: garnish with lime wedges or salt-rimmed glasses for a festive touch before serving.
