Baking Powder (Best Option)
3 times the amount of baking soda (e.g., 1.5 tsp baking powder per 0.5 tsp baking soda)Baking powder contains both an acid and a base, providing a balanced leavening reaction similar to baking soda but without needing an external acid. In fried rice, this helps create a light texture and prevents heaviness.
Use slightly more baking powder than baking soda to achieve the same leavening power. Monitor the salt content since baking powder contains sodium bicarbonate and acid salts.
The final fried rice will be slightly less alkaline but maintain the desired fluffiness and mild texture enhancement, making it the closest substitute in this context.
