⭐ Cornstarch (Best Nut-Free Option)
1 tablespoon cornstarch per 1 tablespoon arrowroot powderCornstarch works well because it gelatinizes at a similar temperature to arrowroot and creates a smooth, translucent sauce that complements chili's texture without cloudiness or off-flavors.
For best results, mix cornstarch with cold water before adding to the chili near the end of cooking to prevent lumps and avoid overcooking, which can break down the starch.
Compared to arrowroot, cornstarch is slightly less stable under acidic conditions but performs well in chili, maintaining a desirable thick consistency and appearance.
