The old recipe cards are full of instructions that a modern reader finds infuriating. Bake until it’s the right colour. Add flour till it feels right. Cook until it smells done. A moderate oven. No temperatures, no times, no cup measures — just these maddening, sensory, seemingly useless directions that assume you already know the answer. We read them as imprecise, as evidence that the old cooks were vague, that the recipe is incomplete. And I want to flip that all the way over, because I’ve come to believe the exact opposite is true: until it’s the right colour is a more honest and more accurate instruction than bake for 22 minutes, and our worship of the precise number is the real imprecision.

Here’s the thing the number pretends and the sensory cue admits. “Bake for 22 minutes” is false — or at least, false the moment your kitchen stops being identical to the recipe writer’s. Your oven runs hot or cold. Your pan is darker or thinner. Your kitchen is humid today. Your brown sugar is more packed. The pie doesn’t care what the clock says; it’s done when it’s done, and “done” is a physical state — a colour, a set, a smell, a wobble — that 22 minutes only approximates, and only in one specific kitchen on one specific day. The number gives you the comforting feeling of precision while quietly lying about the actual target. “Until it’s the right colour” refuses the comfort and names the real target directly: the food is finished when it looks finished, because doneness was always a sensory fact and never a temporal one. The vague instruction is pointing at the truth. The precise one is pointing at a proxy for the truth and hoping you don’t notice the gap.

We prefer the number for a reason, and it’s worth being honest about: the number requires no skill. It offloads the judgment onto the clock so the cook doesn’t have to develop an eye. And that’s a real convenience — it’s why recipes standardized, why measurement got exact, why we can hand a total beginner a set of numbers and get an edible result. I’m not against it. But we should be clear about what the trade actually was. We didn’t gain precision. We traded one kind of knowledge for another — traded the cook’s trained senses for the recipe’s fixed numbers, moved the expertise out of the person and into the instructions. The old cards demand you bring the skill. The new ones promise you don’t have to. And in taking that promise we quietly agreed to stop learning the thing the old cooks knew: how to read food directly, with your eyes and nose and hands, instead of through the mediating fiction of a timer.

Which is why “until it’s the right colour” isn’t a gap in the recipe — it’s the recipe trusting you, or rather assuming you’ll become someone worth trusting. It presumes a cook who will make the dish enough times to learn what the right colour is, who will develop the eye, who will graduate from needing the number to reading the food. It’s not vaguer than the modern version. It’s addressed to a more skilled reader — one the modern recipe has given up on ever producing, because it’s easier to sell precision to a beginner than to cultivate judgment in one. The old card is harder because it respects you more.

So the next time a handwritten card tells you to cook something until it looks right and you feel that flash of frustration — no time, no temperature, how am I supposed to know — sit with the possibility that the card is being more honest with you than any tested, timed, temperature-controlled modern recipe ever is. It’s telling you the truth that the numbers hide: that doneness lives in the food, not the clock, and that the only real way to know is to learn to see. Make the dish enough times to earn the eye the card assumes you have. Then “until it’s the right colour” stops being vague and becomes the most precise instruction there is — a direct pointer at the actual thing, from a cook who trusted you to eventually be able to look.
