I started with halving the amount of syrup the original recipe called for, from 60g to 30g. The sweetness drastically improved - from obviously teeth rotting to ninja teeth rotting (to be honest, this is a sugary drink). So, I kept the syrup level there since it is a nice balance between the butterbeer flavour and the cream soda flavour.
Next, I rounded up some different brands of cream soda I could find. I even went to Winner's to get a hold of one. My testing line up is:
- Schwepp's
- Jones
- Stewarts
- Boyland
I stayed the hell away from any pink cream sodas as that is guaranteed to be atomically teeth rotting. Also, the fact that pink cream sodas taste funny to me, maybe because I see that it's pink and NOTHING SHOULD BE NATURALLY NEON PINK!!!
