Start with a cocktail glass of your choosing. Yiayia uses a “tulip” style glass, but any shape will do! If you want, put the glasses in the freezer for about 10-15 minutes. This gives you the effect of a chilled glass and keeps the drinks colder for longer!
Put a scoop of ice in each glass and fill halfway with the soda of your choice.
Top the glass to ¾ with orange juice and add enough grenadine to your liking.
Garnish with a Maraschino cherry (or three!) and enjoy!
