I would like someone to look into this further, the earliest mention I could find of someone saying they made a meringue out of chickpea foam is from May 29, 2012 at 16:29 at this link: https://cooking.stackexchange.com/questions/8041/should-i-re...

It's very clear that it wasn't common knowledge on the internet until 2015-2016.

I grow more and more I am concerned about how much raw data has been lost... when you factor in context even more so.

Having prepared a lot of beans it doesn't surprise me at all.
