A bright snap signals water on a hot surface; a steady hiss means moisture cooking off; a low murmur suggests you’ve entered tender territory. If the sound vanishes, heat is too low; if it screams, lower it. Train your ear, and the pan narrates what to change next.
Golden edges indicate sugars browning, glossy sheen hints at emulsification, and persistent billowy steam tells you moisture remains. When color deepens but steam wanes, concentrate flavors with a splash of stock or wine. Observation becomes timing, freeing you from strict clocks and transforming uncertainty into clarity you can plate.
