⭐ Club Soda (Best Vegan Option)
Replace liquid component with equal volume of club soda (e.g., 1/4 cup club soda per 1/4 cup water) Quick tip: Adds some lightness and bubbles but lacks chemical leavening, resulting in less crispness.
Club soda contains dissolved carbon dioxide which can create bubbles in the batter or coating, adding some aeration and lightness during frying.
Use it to replace the liquid portion of the batter or marinade to introduce bubbles. However, it does not chemically react with acidic ingredients to produce sustained leavening.
The crust will be less crisp and more prone to sogginess compared to baking soda, making it a less effective substitute but still useful when chemical leaveners are not an option.
