To make this Thai Fish Sauce Recipe gluten free, use a certified gluten-free fish sauce, as some brands may contain wheat-based additives or be processed in shared facilities. Verify that the granulated sugar and any bottled lime juice, if used, are gluten free. Serve with gluten-free dishes such as plain rice, grilled meats, seafood, or gluten-free noodle dishes. Use clean utensils and bowls to prevent cross-contact.
