alt Hacker NewsI think in many dishes you can add quite a lot, but it blends and cooks in with other ingredients so that the "fish sauce flavor" does not jump out as such.
I make mapo tofu with 1 tsp each of fish sauce, oyster sauce and light soy sauce. I don't think anyone would think it tastes like fish or oyster sauce in any way, but it doesn't taste right at all without them. The same goes for many other dishes.
I need to try this. Typically I make my mapo tofu with dry-fried mushrooms and mushroom stock (I've found this much tastier than a pork or beef-based mapo tofu), but I don't always have the mushroom preparation on hand and punching up a pork mapo tofu with fish sauce would be much more convenient.
What kind of fish sauce do you use?
