Why add what we add?

In my recipe I use a number of things, I will name them, and tell you why I use them.

Maltodextrin, it adds mouthfeel to the soda

Malt, dried malt extract adds a head to soda that beer has

Cane sugar, it adds complexity to the soda, giving it depth

Half cream soda, I like to add half cream soda extract to RB to give it a rich tastet to it
