Baking Soda and Cream of Tartar (Best Option)
1/4 teaspoon baking soda + 1/2 teaspoon cream of tartar per 1 teaspoon baking powderThis combination mimics the chemical leavening reaction of baking powder by providing both an acid (cream of tartar) and a base (baking soda). In chili, this helps maintain the desired texture and acidity balance, enhancing the overall mouthfeel.
To ensure success, mix the two powders thoroughly before adding to the chili. Since chili is a slow-cooked dish, the reaction will occur gradually, helping to tenderize ingredients subtly.
Compared to commercial baking powder, this substitute offers a clean, neutral taste and preserves the chili’s intended savory profile without introducing off-flavors.
