You Say Soda, I say Powder...

Just call the whole thing off.

The Kitchn had a very informative article on the difference between baking soda and baking powder.

"Baking soda, baking powder - what's the difference? Both are white powders, odorless and nearly indistinguishable. Yet both help your baked goods to rise. Without them (or another leavener like yeast or beaten egg whites) all of our breads and cakes would be very flat and dense.

We were curious about why recipes call for one over the other, and we went on a hunt to find out.

Go on over and check out out what they found.
