⭐ Soy Sauce (Best Fat-Free Option)
1 teaspoon per 1 tablespoon of Fish SauceSoy sauce contains amino acids and glutamates that mimic the umami profile of fish sauce, enhancing the bread's flavor complexity. Its liquid form integrates smoothly with sourdough dough, supporting fermentation without inhibiting yeast activity.
When using soy sauce, reduce additional salt slightly to avoid over-salting, and ensure it is well mixed to distribute flavor evenly. Opt for low-sodium soy sauce if salt control is critical.
Compared to fish sauce, soy sauce imparts a slightly different but still savory note, maintaining the bread's characteristic tang and depth without introducing fishy aromas.
