Put all ingredients in a blender, puree until smooth.
Chill completely if using a freezer bowl type ice cream freezer (see notes).
Freeze in ice cream maker, according to directions. It is a somewhat soft consistency, so for a scoopable (harder) freeze, stash in the freezer for a few hours before serving. My photos were taken immediately after the ice cream maker stopped.
Notes
For best results with a freezer bowl type freezer, start with very cold sorbet mix. You can stick it in the freezer to quick chill. You can also start with chilled ingredients.I suggest tequila, but we have also used mezcal, and we love the hint of smoke.I use Triple Sec for desserts as the quality isn't that important, and it's pretty inexpensive.Calories are an approximation from MyFitnessPal.com and based on 3 servings.
