Nutrition Tips
- Use sparingly as a single tablespoon contains over 60% of the recommended daily sodium intake.
- It is an excellent source of umami, which can help you feel satisfied with smaller portions of food.
- Look for brands with minimal ingredients (fish and salt) to avoid unnecessary additives or MSG.
- Because it is so salty, you can often omit additional salt from recipes when using fish sauce.
- Store in a cool, dark place; while it doesn't spoil easily, its flavor profile can change over time if exposed to heat.
