Soy sauce

Fish sauce can be substituted with soy sauce, which is prepared from fermented soybeans, water, salt, and wheat. It is also appropriate for vegetarians. Because soy contains amino acids, soy sauce has a deep umami taste with a touch of sweetness. To add flavor, consider substituting fish sauce for soy sauce in a 1:1 ratio or combining soy sauce with additional ingredients:

• Minced anchovy. Mix 1 tablespoon (15 mL) soy sauce and 1 minced anchovy fillet.
• Rice vinegar. Use a 1-to-1 ratio of soy sauce and rice vinegar for extra freshness.
• Lime juice. Add 1/2 teaspoon of lime juice to every 1 tablespoon (15 mL) of soy sauce.

You should cut back on the additional salt you use in your recipe since soy sauce could be overly salty for some meals. By using rice vinegar or chopped anchovies, soy sauce may also be made to taste better. With these factors in mind, you may use soy sauce in the same amount that you would use fish sauce and your cuisine would still taste delicious.
