Fill a glass with ice and then pour the grenadine directly over the top.
Next, slowly pour the ginger ale into the glass.
Garnish your drink with cherries. Serve immediately.
If you prefer a Dirty Shirley, simply pour one ounce vodka over the ice prior to adding the grenadine and ginger ale. Garnish with maraschino cherries and a sliced lime. Stir and enjoy!
Switch out the ginger ale for 6 ounces of pink moscato champagne for an adult version of this fizzy sweet drink.
Although, true grenadine is not cherry-flavored, in a pinch, you could use the heavy cherry syrup from the maraschino cherries jar, which would be similar to Rose's grenadine. You may also use pomegranate juice or cherry juice cocktail if needed.
