Notes

This substitute is highly effective but must be used immediately once combined with any liquid ingredients in your main recipe, as the leavening reaction begins upon hydration. Ensure your baking soda and cream of tartar are fresh; old leavening agents significantly reduce their potency, impacting the lift and texture of your baked goods. Store individual ingredients in airtight containers in a cool, dark place to maintain their efficacy. The cornstarch acts as a stabilizer, preventing premature activation and absorbing moisture, similar to commercial baking powder formulas.
