First make the simple syrup, and allow time for it to cool.
Combine the sugar with a cup of water in a small pot and simmer, stirring, until it is clear. Let cool. Damien puts it in a mason jar and refrigerates it.
Prepare the glasses. Mix sea salt or kosher salt and sugar in a saucer and add a little lime juice to wet it. Rub a lime wedge along the edge of the glass and roll it in the salt and sugar mix.
To make the margaritas, put some ice cubes in a cocktail shaker or mason jar. Add three parts tequila, two parts lime juice, one part Triple Sec, one part simple syrup. Shake until the lid gets cold. Pour the liquid into prepared glasses.
