Is there a name for a cocktail using rum, Fernet, and Disaronno?

While the provided list of cocktails does not specifically include a combination of rum, Fernet, and Disaronno, you certainly have an interesting mix of ingredients that could create a unique and intriguing drink. Let's look at how these ingredients could blend together:

• Rum: It is known for its varied flavor profiles which can be influenced by whether it's dark, spiced, or light. Each kind would bring a different note to the cocktail.
• Fernet: Known for its strong, bitter, and vegetal characteristics, it could add a sophisticated herbal complexity to the drink.
• Disaronno (Amaretto): This would introduce a sweet, almond-like flavor that could balance the bitterness of the Fernet.

Combining these three could result in a cocktail with a balanced contrast of sweet, bitter, and rich flavors.

While there's no pre-existing name for this mix in our provided information, you could certainly create your own signature drink. Perhaps you could call it something evocative like the "Herbal Almond Rum" or the "Bitter-Sweet Pirouette."

Feel free to experiment with proportions, but a good starting point might be:

• 30ml Rum
• 15ml Fernet
• 15ml Disaronno

Stir these together in a lowball glass over ice and garnish with a twist of citrus to brighten the complex flavors. Enjoy your custom cocktail creation! :)
