Why do muffins need salt?

* Flavor enhancer: Salt helps to bring out the flavors of the other ingredients in the muffin, making them taste more delicious.

* Tenderizer: Salt helps to weaken the gluten in the flour, which makes the muffins more tender.

* Leavening agent: Salt can also help to leaven muffins by reacting with the baking powder or baking soda to produce carbon dioxide gas.

* Crust color: Salt can help to give muffins a golden brown crust by promoting the Maillard reaction, which is a chemical reaction between amino acids and sugars that occurs when food is heated.
