โญ Club Soda (Best Vegan Option)
Replace 2 tablespoons of liquid with 2 tablespoons of club soda per 3 eggsClub soda contains dissolved carbon dioxide which can introduce bubbles into the egg mixture, helping to lighten the texture of the frittata. It does not chemically leaven but can improve airiness when whipped into the eggs.
Use chilled club soda and fold gently into the eggs to retain carbonation. This method works best combined with vigorous whisking to trap air.
The texture will be subtly lighter but less pronounced than with baking powder, and there is no flavor impact.
