⭐ Soy Sauce with Lime Juice (Best Fat-Free Option)
1 tablespoon soy sauce + 1 teaspoon fresh lime juice per 1 tablespoon fish sauceSoy sauce offers a rich umami base similar to fish sauce due to its fermentation process, while lime juice introduces the bright acidity that fish sauce naturally has from fermented fish. This combination balances salty and tangy notes essential for enhancing burger patties.
For best results, use low-sodium soy sauce to avoid excessive saltiness and add lime juice just before mixing into the meat to preserve its fresh acidity. Adjust lime juice slightly to taste depending on the burger seasoning.
Compared to fish sauce, this substitute provides a slightly less pungent but equally savory profile, maintaining the burger’s juicy and savory character without introducing fishy notes.
