Add four ounces of lemon lime soda and ginger ale to each glass.
Add one tablespoon of grenadine syrup, and one teaspoon of the maraschino cherry juice to each glass and stir.
Add some ice and top off the drink with maraschino cherries.
Notes
Sweetness: Start with a little less grenadine, then add more to taste. A little goes a long way.
Cherry juice: A splash of the maraschino cherry juice deepens the pink color and adds a little sweetness.
Swaps: Diet lemon-lime soda and sugar-free grenadine both work. Club soda can replace the ginger ale, but you’ll lose a little of the gingery bite.
Make it a Dirty Shirley Temple: Add a shot of vodka to each glass.
Serving a crowd: Mix everything in a pitcher without the ice, and let everyone pour their own over ice. Adjust the total servings on this recipe card for updated ingredient amounts.
Storage: Best made fresh since the soda goes flat. Leftover grenadine and cherry juice keep in the fridge.
