Rainbow Collins Recipe

Prepare glass

Fill a highball glass or Collins glass with ice to chill while you assemble the drink.

Mix juices

In a cocktail shaker (or a large mixing glass) add the orange juice (3 oz) and pineapple juice (2 oz). Do not add soda yet.

Shake

Add a handful of ice to the shaker, secure the lid, and shake vigorously for 8–10 seconds to chill and slightly dilute the juices.

Strain into glass

Discard the ice from the chilled serving glass, then fill the glass about three-quarters full with fresh ice. Strain the shaken juice mixture into the glass over the fresh ice.

Add soda

Top the juice mixture with 7-Up (2 oz). Pour slowly to preserve carbonation and create slight layering.

Create the rainbow effect

Carefully pour the grenadine (0.5 oz) slowly down the inside edge of the glass or over the back of a spoon so it sinks to the bottom and creates a red-to-orange layered effect.

Garnish and serve

Finish with an orange slice or pineapple wedge on the rim and an optional maraschino cherry. Serve with a straw and encourage the guest to stir before drinking if they want a uniform flavor.
