1. Place ice cubes, Tequila, Cointreau, lime juice and watermelon into blender and whiz until smooth.
2. Place salt on a flat plate. Wet the rims of glasses with the lime wedge all around and dip into the salt so it coats the rim of the glasses. Pour the drink into each glass and garnish with lime wedge. If using the Tabasco sauce, hit with a few dashes into each drink.
3 handfuls of ice cubes (fill up to .75litre line in blender)
180ml Tequila Blanco
6 tsp fresh lime juice
1 mini watermelon, rind and seeds removed, cut into chunks (800g after cutting rind)
Lime wedges to garnish
Sea salt for rim of glass
Tabasco to garnish (optional)
