Soy Sauce with Lime Juice and Dried Seaweed (Best Option)
1 tablespoon soy sauce + 1 teaspoon lime juice + 1/4 teaspoon finely crushed dried seaweed per 1 tablespoon fish sauceSoy sauce provides the salty and umami base similar to fish sauce, while lime juice adds acidity to mimic the brightness. The crushed dried seaweed contributes a mild marine flavor that replicates the briny depth of fish sauce. This combination balances the flavor profile needed in salad dressings.
For best results, use a light soy sauce (not dark) to avoid overpowering color and flavor. Adjust lime juice to taste to maintain acidity balance. Ensure seaweed is finely crushed to avoid texture issues.
Compared to fish sauce, this substitute is less pungent but maintains the essential savory and salty notes, resulting in a well-rounded dressing that is suitable for vegan and vegetarian diets.
