Fish / Oyster Sauce
I have a recipe for lettuce cups I would like to try that calls for oyster sauce. I have fish sauce in my pantry. Are they interchangable?
No. Fish sauce is salty and, for lack of a better word, fishy. Oyster sauce is briny and somewhat sweet. If you are going to sub fish sauce for oyster sauce, you may want to decrease the amount you use and balance the flavor with a little sugar.
Don't use fish sauce as a substitute.
If you don't have oyster sauce, you can replicate the flavor by combining the following and making a "fake" oyster sauce:
1. Dark soy sauce
2. Brown sugar
3. Rice vinegar
4. Maggi sauce or Worcestershire sauce
Combine and bring to a boil in a saucepan, and then simmer for about 10 minutes at low heat.
