Vermouth Royale

Step 1

Add the lime wedges, one of the lemon peels, sugar and salt to the bottom of a cocktail shaker. Use a muddler (or the end of a wooden spoon) to lightly smash and release the lime’s juices and the lemon’s oils and to dissolve the sugar and salt.

Step 2

Add the vermouth and crème de cassis, and fill the shaker with ice. Cover and shake until very cold, then strain into a Collins glass filled with ice. Top with sparkling wine and garnish with the second lemon peel.
