Step 1: Prepare Your Glass
Choose a tall glass like a highball, hurricane, or Collins glass to highlight the layered sunset effect. Fill the glass about ¾ full with fresh ice cubes.

Step 2: Add the Grenadine
Pour 0.5 oz of grenadine directly over the ice. Since grenadine is denser than the other ingredients, it will naturally settle at the bottom, forming the base layer of your radiant horizon.

Step 3: Combine Juices
In a separate small mixing cup or shaker (no need to shake), combine 1 oz orange juice, 1 oz pineapple juice, and 0.5 oz fresh lime juice. Stir gently to combine. If making a cocktail version, add 1.5 oz of your chosen spirit to the mix at this stage.

Step 4: Layer the Juices
Slowly pour the juice mixture over the back of a spoon or gently down the side of the glass so it rests on top of the grenadine without disturbing it too much. You’ll see the layers begin to build, with orange and yellow tones creating a beautiful gradient above the red base.

Step 5: Top with Bubbles
Finish with 2 oz of sparkling water or lemon-lime soda. Pour slowly to preserve the layers and avoid excess fizz. The soda should sit on top of the juices, creating a light, bubbly finish.

Step 6: Garnish and Serve
Garnish with an orange slice on the rim, a maraschino cherry dropped into the glass or skewered, and a fresh mint sprig for a fragrant touch. For a dramatic twist, serve with a straw and let the drinker give it a gentle stir to swirl the colors just before sipping.
