"Customers at gourmet coffee shops may notice a cold beverage option called an
Italian soda, also known as a creamosa or French soda in different parts of the
world. An Italian soda is a refreshing combination of flavored syrup and club
soda or seltzer water mixed in a cup of ice. The addition of half-and-half or
milk turns an Italian soda into a creamosa or French soda. Some coffeehouses add
a dollop of whipped cream to an Italian soda to create a creamier texture."
First take some sparkling water or seltzer water, some ice in a glass, and about 1/2 to 1 jigger of your favorite flavored syrup
Pour the water into the glass. Leave room to add the syrup. Some like adding the syrup first. It is a matter of taste!
