The Blackthorn Irish is a classic cocktail that combines the rich flavors of Irish whiskey with the sweetness of sloe gin, creating a smooth and refreshing drink perfect for any occasion.
Pour in the Irish whiskey, sloe gin, sweet vermouth, and Angostura bitters.
Shake well for about 15 seconds until the mixture is chilled.
Strain the mixture into a chilled coupe or martini glass.
Garnish with a twist of lemon peel, expressing the oils over the drink before placing it in the glass.
Notes
For an extra touch, consider using a high-quality Irish whiskey and sloe gin to enhance the flavors. Adjust the sweetness by varying the amount of sweet vermouth to your taste.
