So smooth and rich, yet with a kick…

What’s not to love when three of a recipe’s primary ingredients are rum, butter, and sugar. That’s the decadent deliciousness of hot buttered rum. So smooth, rich, and flavorful. But this spicy hot buttered rum recipe adds a little something extra. A dose of cayenne pepper lights a simmering flame to the smooth taste. This is a winter cocktail that warms you to the core.
