It doesn’t necessarily need to be a margarita glass but can be a tumbler instead. Start by rimming the glass with the sea salt by moistening it first in lime juice and then rolling it in the salt. Often made with Cointreau, consider experimenting with different triples secs for a unique result. Although its distinctive glassware may have played a role, the Margarita is one of the most famous summertime cocktails out there.
