What unique element is used to garnish the LoHi Spritz?

The unique element used to garnish the LoHi Spritz is dehydrated lemon. This choice stands out because dehydrated fruits often provide a concentrated flavor that complements cocktails while also offering a visually appealing addition. Dehydrated lemon adds an aesthetic element to the drink without introducing excess moisture, which can dilute the cocktail. It enhances the presentation and helps highlight the citrus notes in the spritz recipe, creating a balanced and attractive beverage.

The other choices, while common garnishes in cocktails, may not provide the same distinctive look or flavor impact as dehydrated lemon. Fresh mint, for instance, is often used for its aroma and freshness but is more typical in other cocktail varieties. An orange wheel adds a classic touch but is quite common in various drinks, while lemon zest can enhance flavor but lacks the visual uniqueness that dehydrated lemon provides. Therefore, dehydrated lemon is the standout garnish for the LoHi Spritz.
