I have to agree. A handful of times during my life that I had some bad heartburn but no antacids I used the tried and true method of a teaspoon of baking soda mixed in a shot of water and slammed it back. It tastes horrible. Even a teaspoon is so strong in taste I guess I would describe as salty. And no I did not feel unwell but my heartburn got better.
And as a kid I once mistook 1/2 teaspoon baking soda and added 1/2 cup to a batch of cookies. The taste was so noticeable and disgusting the only option was to throw out the cookies.
So a teaspoon is a home remedy, a half cup is impossible to ignore, I just don't understand how this report about it in the food could be true.
Ahhhh! Mystery solved. About 40 yrs ago I came to work to taste the most foul cookie (pretty cookie at that!). This is what they must have done. Nobody admitted to making the cookies. I always thought it was a gag. LOL
