Define "cocktail garnishes."

Cocktail garnishes refer to edible decorations that are strategically placed in or on a drink to enhance both its presentation and flavor. They can include a variety of items such as fruits, herbs, spices, or even flavored sugars. The inclusion of garnishes not only makes the drink visually appealing but can also add a complementary taste or aroma, enhancing the overall drinking experience.

In the context of bartending, understanding the purpose and use of garnishes is essential for crafting cocktails that not only taste good but also look inviting to customers. This attention to detail can greatly influence the perception of the drink and may even serve as a signature feature of a bartender's style.

The other choices do not align with the definition of cocktail garnishes: ingredients used to add sweetness pertain to flavor profiles rather than decorative elements, non-edible decorations don’t fulfill the criteria of enhancing both visual and flavor aspects, and utensils for stirring are tools rather than embellishments for drink presentation.
