The Food Based Holidays Approach with many questions...

I have been mulling over writing about some of the FAQ to the Minnetonkascenes"Hapless chef".
An example is the FAQ: "Can I substitute baking soda for baking powder?"
The hapless chef replies: "There is no difference between baking soda, and baking powder. It is one of the myths foisted upon us by the large Multi-national Food Conglomerates. The truth is that you can also substitute Alka-Selzer for either one"

What do you think? Is this tip of value to anyone?
