Everything works
until one thing
runs out.

One oven, one cook, and however many people said yes. I write about the part that comes after the recipe — how much, how far ahead, what holds and what collapses — and I built three tools that do the counting. They count the racks, the burners, the cold space and your own two hands, and they name whichever one gives out first. When the night does not fit the kitchen, they say so instead of picking a number. That is the useful part.
