Rule 1 of 27 · Chapter I — Before You Cook
Read the whole recipe before you start
Why this rule exists
Most kitchen disasters are decided before the first pan is touched, in the moment you skimmed the ingredient list and dived in. A recipe is not a wall of text to consume line by line as you go; it is a plan with a shape, and the shape only reveals itself if you read to the end first. Halfway through you discover the dough needed to chill an hour, the oven should have been preheating, or you are meant to have three things happening at once and have started them in the wrong order. Reading first turns a recipe from a series of surprises into a route you have already walked in your head. It costs two minutes and saves the panic of realizing, too late, what the writer assumed you already knew.
In practice
Before anything comes out of the fridge, read the recipe start to finish, twice if it is unfamiliar. Note the verbs that hide time inside them: chill, marinate, rest, proof, reduce, cool completely. Check the equipment against what you actually own, and the timing against the clock you actually have. Mentally place the steps that must overlap, so the pasta water is already boiling when the sauce is nearly done. If a step confuses you, sort it out now, at the counter with clean hands, not later with sauce on your phone. Then set the recipe somewhere you can see it and begin.
When it doesn't apply
A dish you have cooked twenty times lives in your hands, not on the page, and needs no ceremony. And some rustic cooking is meant to be improvised rather than followed; there the recipe is a suggestion, not a route. The rule is for anything new, precise, or timed.
