I suspect this shit originates with social media influencers representing companies selling flavoured salt. One company in particular likes to try and mythologize it. Many countries have seasoned salt since long before us. We mostly only put it on chips and people are split on whether they like it or not. I would prefer gravy and cheese or better still put the chips in an AB/HSP. I think it is hugely overrated. In actual cooking and other snacks we still use MSG and other sources of umami like fish sauce, soy, bouillon etc.

Nobody is putting chicken salt on their sushi, kebab or banh mi or the hundreds of other takeaway foods we eat that aren’t chips and actually taste good. Chicken salt is boring mainstream manufactured culture like the Bunnings sausage sizzle. People have been cooking and selling food for community fundraisers for generations but it took a hardware company to nudge it on social media to make it a talking point. Reddit/Facebook level shit.
