Tamari (Best Option)
1 tablespoon per 1 tablespoon soy sauceTamari is a Japanese soy sauce variant that is typically gluten-free and has a slightly richer, less salty profile than regular soy sauce. It works well in chili because it preserves the umami depth and salty balance that soy sauce contributes, enhancing the meatiness and complexity of the dish.
When using tamari, measure it 1:1 to soy sauce. Because it is slightly less salty, you may want to adjust salt levels after tasting. It integrates seamlessly without altering the chili’s texture or color.
The final chili will have a very similar savory depth and richness, with a slightly smoother finish compared to regular soy sauce, making it the best alternative.
