How can I effectively layer a cocktail to create a visually appealing and delicious drink?

To effectively layer a cocktail, use a spoon to pour each ingredient slowly over the back of the spoon into the glass. Start with the heaviest ingredient at the bottom and work your way up to the lightest. This will create distinct layers. To make it visually appealing, choose ingredients with contrasting colors and textures. Experiment with different combinations to find the perfect balance of flavors.
