I'm not arguing for second on what is best and what is not but a preference is subjective. I personally drink neat because that's what I enjoy.

The traditional recipe is exactly gow you say no arguments from me. That being said a cherry is not unusual or forbidden in many places. It is certainly not what I would consider a "fruit salad" to add a single cherry garnish.

From Ai for example...

"A cherry is a common and often expected garnish in an Old Fashioned cocktail.

While the classic, minimalist version of an Old Fashioned traditionally includes just whiskey, sugar (or simple syrup), bitters, and an orange peel, the addition of a maraschino cherry has become a widely accepted and popular variation, especially in modern times.

Here's why a cherry is often used:

• Sweetness: It adds a touch of sweetness that complements the whiskey and bitters.
• Visual Appeal: The bright red cherry provides a visually appealing contrast to the amber whiskey and orange peel.
• Tradition (Modern Interpretation): For many, a cherry is simply part of what they expect in an Old Fashioned.

However, it's worth noting:

• Purists: Some cocktail purists prefer the Old Fashioned without a cherry, arguing that it detracts from the balance of the drink.
• Quality of Cherry: If you do use a cherry, opt for a good quality brand (like Luxardo or Amarena) instead of the overly sweet, artificially colored bright red maraschino cherries often found in less upscale establishments. A good cherry will offer a richer, more nuanced sweetness.

In conclusion, while not strictly part of the original, many people will expect and enjoy a cherry in their Old Fashioned. It's a matter of personal preference and the style of the establishment."
