⭐ Club Soda (Best Vegan Option)
Replace 1/4 cup liquid with 1/4 cup club soda per 1 teaspoon baking powder Quick tip: Introduces carbonation to help with lightness but provides weaker leavening.
Club soda contains dissolved carbon dioxide, which can introduce some bubbles into the batter, aiding in lightening the texture of the frittata. However, it lacks the chemical leavening power of baking powder.
Use immediately after mixing to retain carbonation. This method works best in combination with gentle folding or whipped egg whites.
The resulting frittata may be less risen and slightly denser than with baking powder, but still lighter than no leavening.
