Prepare the glass by rubbing a lime wedge around the rim of a margarita glass. Then dip the rim into sherbet powder to coat, giving a fizzy, nostalgic edge. Mix the drink by filling a cocktail shaker with ice. Add tequila, orange liqueur, lime juice, and cherry syrup. Shake well for 15–20 seconds until chilled, then strain into the sherbet-rimmed glass filled with fresh ice. Garnish with a lime wheel and cherry skewer. Serve.
