How to measure fish sauce accurately
For the most reliable baking results, weigh fish sauce on a kitchen scale rather than scooping by volume. One US cup of fish sauce weighs about 255 grams (8.99 oz), but the exact figure changes with how tightly it's packed and the brand. Scooping straight from the bag compacts fish sauce and can leave you 15 to 20% over, so spoon it into the cup and level it off for the closest match to the figures above. Use the tables for quick reference, or the converter for any custom amount in cups, grams, ounces or tablespoons.
Tip: Add fish sauce sparingly and taste as you go — its salty, funky punch mellows into background savouriness but is easy to overdo.
