I'm curious on this! Is taste and salt level somewhat subjective/does it vary from palette to palette, or is there an average "baseline" for say, 75 percent of the population all the way around?
Like, my family hosted Asian foreign exchange students twice for 6 months each. And for the life of us, all our desserts, even mild cheesecakes we tried to serve them, were way "too sweet". For us they were just fine. But that's because we, like many Americans I know, were used to insanely sugary confections.
Could salt be a similar issue where, say, a whole country or large demographic of people is just "used to more" of it potentially? Or is this just me blowing smoke?
I don't smoke!
