The whistle
No Indian recipe says "cook for eighteen minutes". It says three whistles, and everyone knows exactly what that means.
It is a genuinely good unit. A whistle isn't a measure of time — it's a measure of the cooker having reached pressure and held it, which is the thing that actually matters and which a clock can't tell you. Altitude, quantity, how old the dal is: the whistle adjusts for all of them automatically.
It's also audible from another room, which is the real innovation. A woman can start dal, go and hang the washing, and come back at the third whistle. The kitchen calls out. Nobody has to stand there.
Every household has a private dialect of it. Three for toor dal, five or six for rajma and chana, one and switch it off for rice. Arguments about the correct number of whistles for a particular dish can last a generation and are never settled.
And the sound itself: the hiss building, the rattle, then the sharp release. It is the single most domestic noise in South Asia — the sound of somebody's mother in the next room, which is why Desi people abroad sometimes buy the noisy old aluminium model instead of the quiet modern one, and know exactly why they did it.
Kitchen equipment — why the pressure cooker is the highest-value thing in the kitchen, and dals explained, which is what it's mostly doing.
