What can I say, we made this up. It was so good I had to share. Now, I do not mean to suggest that my husband and I were the first people to add vodka and some extra grenadine to a Shirley Temple, but I think we were the first to call her a slut because of it.
1 ounce of vodka 1.5 ounces of grenadine 4 ounces lemon-lime soda ice
Pour the first three ingredients over ice and stir until well incorporated.
Top with maraschino cherries, a slice of lemon, or nothing at all.
