Combine the tequila, lime, agave, and chilli tincture in a blender. Add ice (or 2.5 oz. of water per Dos-A-Rita for the frozen machine) to the same liquid level in the blender. Use a freeze machine or a blender to mix. For the chabela glass’s rim, add citrus salt. Place a bottle of Dos Equis Lager upside down on top of the frozen mixture in the glass.
