Prep your margarita glass by running a slice of lime around the rim of the glass, then turn your glass upside down and press the rim into a plate sprinkled with salt. Place ice cubes into the glass.
Add the tequila, triple sec, lime juice, pomegranate juice and some ice to your cocktail shaker.
Shake well for 15–20 seconds.
Strain into your prepped glass. Garnish with a lime slice and sprinkle over some pomegranate seeds if desired.
