Hi, I work at a science center where we make homemade soda all of the time...Usually root beer, cream soda, vanilla cola, and raspberry cola. But we have a ton of different extracts (orange, lemon lime, ginger beer) and we would like to use those, too. We've tried making them with vanilla, lemon juice, etc. and they don't turn out well. Does anyone have good recipes or suggestions for any of those extracts?
We usually make 8c of soda with 1c of sugar and carbonate it with dry ice.
