The naration says "when two brothers boiled wheat" . This is confusing even if it is true. If true there needs to be an explaination of how corn came into the experiment. Also, when the corn is soaked it is soaked with lime, the mineral, in a chemical break down of protein called nixtamalization. My explaination is clumbsy but "soaking" is very incomplete. Otherwise the whole process is fascinating. I just watched a video of a home cook trying their own idea and it was far too complex. All hail Cornflakes!
