Not baking soda! Use baking powder.
What I read is that baking soda is very unpleasant to eat, giving a metallic flavor. Baking powder is less icky so mixing a little into a dry rub (about 1/3 as much as the salt) is OK. It works to jump-start the browning/crisping process by messing around with the pH of the surface of the chicken skin.
Baking powder
is baking soda with a dry acid (cream of tartar) added. Baking powder sometimes has an aluminum salt* added (I avoid those brands like Calumet and Clabber Girl and use Rumford), which I guess might give it a metallic taste. I find baking soda salty, not metallic, but if you use way too much in a recipe it might taste soapy because it's alkaline.
America's Test Kitchen always uses
baking soda to enhance browning of meat by raising its pH. The tartaric acid in baking powder would partially neutralize the rise in pH. You don't need much. Think lightly dusted small amounts like 1/4 tsp per pound. Personally, I always use baking soda.
Here's a simple recipe for single-acting baking powder if you don't have any in your pantry: To make baking powder, mix one part baking soda and two parts cream of tartar. So, if your recipe calls for 1 tablespoon of baking powder, use 1 teaspoon of baking soda, mixed in with 2 teaspoons of cream of tartar. (Some recipes will also call for 1 tsp of cornstarch, which is used in the commercial stuff to help keep it dry and prevent it from reacting and going bad.)
Food chemist Shirley O. Corriher in her book,
Cookwise, states in regard to the browning (Maillard) reaction: "Three conditions are necessary for this lower temperature browning: proteins, reducing sugars, and a nonacid environment. Acids prevent browning. Little if any browning occurs at a pH below 6. But with low acidity (ideally a pH between 7.8 and 9.2), the more of certain sugars and proteins in a product, the browner it gets.
FWIW, people like Jenise who live in humid areas should always check the viability of their baking powder before baking by adding a little water to a sample. It should immediately fizz, else it's gone bad.
Here's a link to history of baking powder:
