The Hot Ale Flip is a beer cocktail that was created in the late 1600s, making it one of the first known mixed drinks. This autumn version by author Jassy Davis and published in her book Winter Warmers: 60 Cosy Cocktails for Autumn & Winter uses the classic's template of ale, rum, brown sugar syrup, and egg, but it adds a hint of sweet citrus juice and grated nutmeg for more fall flavor and complexity.
Add beer, rum, rich Demerara syrup, lemon juice, egg white, and egg yolk to a saucepan.
Cook over medium high heat for 5-7 minutes while stirring until warmed through.
Pour into a beer mug.
Garnish with grated nutmeg.
