Nutritional Yeast (Best Option)
1 tablespoon per 1 teaspoon yeastNutritional yeast is deactivated yeast that provides a rich umami flavor similar to active yeast but without fermentation. It enhances the savory depth of chili by contributing glutamates that stimulate taste receptors.
For best results, sprinkle nutritional yeast towards the end of cooking to preserve its flavor. Avoid overheating to prevent bitterness.
Compared to active yeast, it does not contribute to leavening or texture changes but significantly improves flavor complexity in chili.
