How it behaves in this recipe
Fish sauce in pad thai provides salty umami depth and helps balance the sweet and tangy elements of the dish. When substituting, you need to replicate both the saltiness and umami that fish sauce contributes to the pad thai sauce. The substitute should be added to the pad thai sauce mixture, not directly to the noodles, and should provide enough saltiness to balance the sweetness of palm sugar and tanginess of lime juice.
