Baking Powder (Best Option)
1 teaspoon per 1/4 teaspoon baking sodaBaking powder contains both an acid and a base, allowing it to release carbon dioxide gas when moistened and heated, which helps to aerate the eggs and create a fluffier texture. Since scrambled eggs lack acidic ingredients, baking powder is a more balanced substitute.
To use baking powder effectively, use about four times the amount of baking soda called for, as it is less concentrated. Avoid overuse, as too much can impart a bitter taste.
Compared to baking soda, baking powder produces a gentler rise and a slightly different flavor profile, but it still enhances the fluffiness of scrambled eggs effectively.
