@CheshireHuman - I've heard that lead tastes sweet. And I've also heard that for this reason, before new world sugar-cane was a thing, wealthy Romans would top culinary dishes with finely grated lead in order to sweeten them.
When considering that lead is a neurotoxin that leads to various forms of psychosis... 🤔 It would explain a lot about mad emperors. 🤦🏻♂️
