Rim your glass using a lime wedge and a mixture of Tajin and coarse salt, and set aside. Add the cubes, tequila and lime juice to a cocktail shaker. Shake until cubes have dissolved. Strain into your rimmed glass. Garnish with a watermelon slice – coat a side of the watermelon slice with the Tajin-salt mixture for extra spice.
