Place salt on a small plate. Rub the rim of your glass with a wedge of lime to moisten. Dip in salt. Set aside.

Muddle cherries and a sprinkle of sugar in a cocktail shaker until well crushed. Add the tequila, the Powell & Mahoney Margarita, a squeeze of fresh lime juice and some ice. Cover and shake vigorously, about 20 seconds. Strain over fresh ice into prepared glass. Garnish with stemmed cherry and a slice of lime.
