Food Coloring is a substance used to add color to food and drinks without altering their flavor. In the context of alcohol and cocktails, food coloring is primarily used to enhance the visual appeal of drinks, making them more vibrant and attractive. It can be used to match a cocktail to a specific theme or event, or simply to make a drink more visually enticing. Food coloring is available in various forms, including liquid, gel, and powder, and can be used in any cocktail where a splash of color is desired. It is important to use food coloring sparingly to avoid overpowering the drink.
