If so, then the answer is no, an immersion blender is going to have a hard time with ice. If you're absolutely determined to try, then bang the ice up into small chunks in a plastic bag, and blend it only after you've added the margarita liquid. But be careful; this could destroy your stick blender blade or motor. (It would be better to try this in a food processor.)

Readers, any thoughts?
