Baking Powder (Best Option)
3 teaspoons per 1 teaspoon of baking sodaBaking powder contains both an acid and a base, allowing it to react and produce carbon dioxide gas when moistened and heated, similar to baking soda's leavening action. In chili, this helps neutralize acidity from tomatoes and other ingredients, balancing the dish's flavor.
To use baking powder effectively, increase the quantity since it is less potent than baking soda. Watch for any slight change in taste due to the additional acidic components in baking powder.
The final chili will have a comparable texture and flavor profile, with a subtle difference in tanginess that generally complements the dish well.
