Watermelon Marga-Granita

Directions

1. Coarsely chop watermelon in chunks and puree in blender until almost smooth, leave some texture
2. Add Tequila, Cointreau and juice of 2 limes to blender and combine
3. Pour into non-reative metal 9x11 pan and cover tightly with plastic wrap and place in freezer for at least 8 hours, breaking up and stirring every 2 hours for a chunky consistency
4. Just before serving, thinly slice remaining lime into slices, rub around rims of martini glasses and coat rim with salt, mound granita in glass and top with lime slice and pinch of salt
5. Alternately, lay lime slice on small plate and scoop granita on top and pinch of salt on top
6. Tastes great if you wish to omit alcohol if you add just a touch more lime juice and a spoonful of agave nectar
