To make this super simple condiment, you need limes. As all good margaritas use. Then just some kosher salt.
There are a few different ways you can get the lime margarita salt to stick to the rim of your glass. For example, run a lime wedge around the rim of the glass, then dip into the salt.
Dip the rim of the glass in agave or honey and then into the salt.
Good news is this simple drink condiment can keep in your bar or kitchen for up to a month!
