The order matters because each step supplies the raw material the next one needs: a fixed list removes weekly indecision, weekly cooking builds a real sample, full meals force you to judge the vegetable honestly, notes and photos preserve that judgement, and only then can a top three be chosen on evidence rather than mood.
Step 1: Write the ten you avoid
Writing the list first turns a vague intention into a fixed roster, which is what stops weeks three through six from being spent deciding what to buy. Walk the produce aisle or a market stall with a note open and spend ten minutes writing down anything you would normally walk past: kohlrabi, fennel, okra, celeriac, romanesco, salsify, jicama, purslane, daikon, mustard greens. Aim for at least six that you can actually buy within a mile of your kitchen this month. A frequent way this goes wrong is listing aspirational items that show up at one farmers market for three weeks in September, or listing things you tried years ago and disliked, which quietly turns the whole sequence into homework instead of discovery.
Step 2: One vegetable, one week
A week is the right interval because it matches how you already shop, and it is short enough that momentum survives a bad result. Pick recipes using no more than five ingredients the first time, so what you taste is the vegetable rather than the sauce. Kohlrabi, for example: peel it, cut into batons, toss with oil and salt, roast at 220C for about twenty-five minutes until the edges brown. The point is not to impress anyone, it is to find out what the thing actually tastes like. What derails this step is choosing an elaborate braise with fourteen ingredients that buries the vegetable completely, leaving you unable to say whether you liked it or just liked the butter.
Step 3: Promote it to the centre of the plate
A side dish is optional by definition, which means a disappointing one gets pushed to the edge of the plate and the meal carries on unchanged. Building the whole dinner around the vegetable forces decisions about portion size, seasoning, and what protein or starch balances it. Fennel works well here: shave it thin, keep it raw, and toss with white beans, olive oil, lemon, shaved parmesan, and torn bread for a real dinner. By this point you have two or three vegetables behind you, so you know roughly how much attention each one needs. The common shortcut is cooking the new vegetable as a garnish and calling it the week's attempt, which satisfies the list on paper but changes nothing about how you eat.
Step 4: Photo plus one honest line
Memory blurs fast, and after four or five attempts you will genuinely confuse which one you liked. Photograph every plate from the same angle in the same light so the images stack up as a comparison rather than a scrapbook. Then write one specific line, not a rating: "okra turned slippery when I stirred it, better left alone in the pan" tells you what to do differently, while "pretty good" tells you nothing. Keep the lines to a single sentence so you actually keep writing them. Photographs get taken and the note gets skipped, and the note is the part carrying information. By the time you reach step five, those lines are the only honest evidence you have about which three dishes deserve a second cooking.
Step 5: Hand the vote to your guests
With honest notes in hand, the top three becomes a real decision rather than a guess based on which recipe sounded nicest. Cook all three the same evening in smaller portions so nobody fills up on the first dish, and plate them plainly without telling guests which one you preferred. Give each person a card to write their favourite on. What matters is not the winner but where the forks go back for seconds, which tells you whether the dish works for other people or only for you. The failure mode here is cooking the three you feel most confident about instead of the three your notes actually ranked highest, which quietly turns a test back into a performance.
A phone reminder vanishes the moment you dismiss it and leaves no trace that the week ever happened. A paper strip taped inside a cupboard door visibly gets shorter as steps are cut away, and the gaps stay in view until the last one is gone. Print it, tape it where you cook, and cut as you go.
