For the readers pondering, where the Hell (ha!) Is he headed with all this?
First, look up an old food additive called MSG. I was introduced to its use at the old Kapok Tree in Clearwater. Whenever I inquired, exactly what this ingredient was, I was told many different things. The best: it makes people thirsty! Kapok sold a couple of those signature drink's, in a take-home hurricane glass!
Now, look up "HEK 293". I do believe a US Patent was issued, probably a provisional one, when issued would be interesting to know? As I understand it, HEK 293 pretty much does exactly what MSG once did for the human tongue/taste buds.
Have fun!
