If you have Watermelon Sorbet, take it out of the freezer 20-30 minutes before you start preparing your Margarita and leave at room temperature.

Put a cocktail glass in the freezer for at least 20 minutes.

This will keep your drink cooler for longer.

Place all the ingredients in a blender that can handle ice and pulse until smooth.

Remove the glass from the freezer and spread some lime juice on the rim of your glass.

Put the salt into a shallow plate and rim the glass in it.

Garnish with a slice of lime and serve immediatelly.
