โญ Soy Sauce (Best Dairy-Free Option)
1 tablespoon per 1 tablespoon of fish sauceSoy sauce contains glutamates that provide umami flavor similar to fish sauce, enhancing the bread's savory profile. Its salt content helps regulate yeast fermentation and gluten structure, critical in yeast bread.
When substituting, use a light or regular soy sauce and avoid dark soy sauce as it can darken the dough and add sweetness. Monitor salt levels in the overall recipe to prevent over-salting.
Compared to fish sauce, soy sauce has a milder aroma and less pungency, resulting in a subtler umami note that complements rather than dominates the bread flavor.
