Pour the grapefruit juice into ice cube trays and place in the freezer for at least 2 hours or until frozen solid.
Once you’re ready to make your frozen palomas, combine grapefruit ice cubes, lime juice, tequila and agave in a high power blender.
Blend on high speed until the frozen palomas are a slushy like consistency. If they taste too tart, add a bit more agave. If they are too thick, add a splash of grapefruit juice.
If desired, serve in glasses with a salt rim and garnish with a grapefruit or lime wedge. Serve cold!
Notes
We used freshly squeezed ruby red grapefruit, but you could also use store bought juice–just make sure that it’s 100% juice.h
