Cut a notch in a lime wedge, then run the lime around the rim of a glass. Dip the edge of the rim into a plate of flaky sea salt (or for a festive look, use our Margarita Salt).
Place the tequila, lime juice, orange juice, and maple syrup in a mixing glass and fill with ice. Stir until cold.
Strain the margarita into the glass with the salted rim. Serve immediately.
