AdS/CFT duality implies that certain large N strongly coupled Conformal Field Theories have an alternate description as weakly coupled gravitational theories. The fluid-gravity correspondence is a well studied implication of the duality - the hydrodynamic excitations of a holographic plasma are related to the long-lived quasinormal modes of the dual blackbrane. We revisit this old problem from the perspective of the Open Effective Field Theory of the simmering hydrodynamic modes. The analysis relies on a novel gravitational saddle to evaluate real-time correlators which is crucial to correctly account for the Hawking fluctuations of the blackbrane in addition to the dissipative quasinormal modes.
