Using a jigger, measure and add whiskey, dry vermouth, lemon juice, grenadine and 2 dashes of orange bitters into the shaker.
Secure the lid on the shaker and shake vigorously for about 15 seconds. This ensures the ingredients are well-mixed and chilled.
Use a strainer to pour the mixture into a chilled coupe glass.
Optional, but you can garnish with a twist of lemon peel or a cherry for an extra touch of elegance.
Notes
Adjust the grenadine and lemon juice according to your taste preferences. A touch more lemon juice can make your cocktail more refreshing, while a bit more grenadine adds sweetness.
