⭐ Soy Sauce with Lime Juice (Best Nut-Free Option)
1 tablespoon soy sauce + 1 teaspoon fresh lime juice per 1 tablespoon fish sauceSoy sauce provides the salty, umami-rich base similar to fish sauce, while lime juice adds the acidic brightness that fish sauce naturally has. This combination mimics the complex flavor profile fish sauce imparts to fried chicken marinades and dipping sauces.
When using this substitute, ensure the lime juice is fresh to avoid bitterness and adjust acidity to taste. Avoid adding too much lime juice as it can start to 'cook' the chicken if left too long.
The final fried chicken will have a slightly different but equally balanced flavor, with a clean umami note and a subtle citrus lift, preserving the crispness and enhancing the savory profile.
