โญ Soy Sauce (Best Dairy-Free Option)
1 teaspoon per 1 tablespoon Fish SauceSoy sauce works as a substitute because it contains glutamates that provide umami similar to fish sauce, enhancing the overall flavor complexity of the cinnamon rolls. The salt content helps balance the sweetness and enrich the dough's flavor.
When using soy sauce, reduce any additional salt in the recipe slightly to avoid oversalting. Use light soy sauce to avoid darkening the dough excessively.
Compared to fish sauce, soy sauce is less pungent and fishy, resulting in a subtler umami note that complements rather than competes with the cinnamon and sugar flavors.
