Many years ago, I spent some time working in Spain, My Spanish was strictly tourist-level, and limited vocabulary made some simple things like shopping a bit of an adventure.
One day, in the hypermart's tea section, I stumbled across a bag of roots labelled "regaliz". Looked interesting, so I bought it. Nice. Very familiar flavor but I couldn't place it. More familiar when sugar was added. Even more familiar when I drank it cool rather than hot.
It wasn't until I got home that I looked it up and discovered why it seemed so familiar: Licorice. Encountering it as a hot tea rather than as flavoring in sweets put me completely off the track.
So: Hot ginger beverage? Sure, why not?
Spice-based sweets used to be much more common in America; they've largely fallen out of fashion in favor (in flavor?) of nut and fruit based confections.
