Pour salt onto a plate. Rub a lime wedge on the rim of a highball glass. Dip the wet edge into the salt. Fill the glass with ice.
Pour the tequila and lime juice into the glass, then top it off with Topo Chico.
Garnish with a lime wedge, and enjoy.
Notes
You can make this directly in the Topo Chico bottle. Rim the bottle with salt after rubbing it with lime, sip a little to make space, then pour in tequila and lime juice.A citrus juicer works best to get the most juice from your limes. Roll the lime on a hard surface and use it at room temperature for easier juicing.Bottled lime juice can be used, but fresh juice gives much better flavor.For a different rim, try sugar or Tajin instead of salt.
