Yes, fish sauce can be a suitable substitute for anchovies or anchovy paste in certain recipes. While fish sauce and anchovies are not identical in flavor, they both provide a savory, umami-rich taste to dishes. Fish sauce is made from fermented fish and has a pungent and salty flavor.
To use fish sauce as a substitute for anchovies or anchovy paste, you can follow these general guidelines:
Measure the substitution: For anchovies or anchovy paste, you can typically use fish sauce in a 1:1 ratio. For example, if a recipe calls for 1 teaspoon of anchovy paste, you can replace it with 1 teaspoon of fish sauce.
Adjust the saltiness: Fish sauce is quite salty, so when using it as a substitute, you may need to reduce or adjust the amount of additional salt in your recipe. Taste the dish as you cook and make any necessary adjustments to the seasoning.
Flavor considerations: Keep in mind that fish sauce has a distinct flavor, and while it can provide a similar umami taste, it may not replicate the exact flavor profile of anchovies. It can work well in recipes like dressings, marinades, stir-fries, and sauces where the strong flavor can blend with other ingredients.
It can add depth and complexity to dishes just like anchovies do. However, the specific results may vary depending on the recipe and personal preferences, so it's always a good idea to taste and adjust as needed when substituting ingredients.
