⭐ Soy Sauce (Best Nut-Free Option)
1 teaspoon per 1 tablespoon of fish sauceSoy sauce contains glutamates that mimic the umami flavor of fish sauce, providing depth without overpowering the biscuit’s mild flavor. Its liquid form integrates smoothly into dough, maintaining the biscuit’s structure.
When using soy sauce, reduce any additional salt slightly to avoid over-salting. Mix thoroughly to ensure even distribution and avoid localized dark spots.
The final biscuit will have a subtle savory note similar to fish sauce but with a slightly different aroma, maintaining the expected lightness and flakiness.
