Is patis and vinegar completely mix?

Patis, a Filipino fish sauce, and vinegar do not completely mix due to their differing densities and compositions. Patis is salty and has a thicker consistency, while vinegar is more acidic and watery. When combined, they may partially blend, but will typically separate into layers if left undisturbed. Mixing them well can create a flavorful dressing or marinade, but they will still retain distinct characteristics.
