Baking Powder (Best Option)
3 teaspoons per 1 teaspoon of baking sodaBaking powder contains both an acid and a base, allowing it to release carbon dioxide gas when moistened and heated, similar to baking soda’s leavening action. In curry, this helps balance acidity and can lighten textures in batter-based or fried curry components.
When substituting, use three times the amount of baking powder to achieve similar leavening. Be cautious not to add excess powder to avoid a metallic or bitter aftertaste.
Compared to baking soda, baking powder is less alkaline, so the curry’s flavor profile remains more balanced, with minimal impact on the final taste and texture.
