A salad has a job

A salad sitting next to smoked pork belly has one job: cut through it. Acid, crunch, something cold. If it also has candied pecans, dried cranberries, three cheeses, croutons and a creamy dressing, it isn't cutting anything. It's a second rich thing on a plate that already had one.

This is the most common way a good cook makes a worse meal. Not by underdoing it. By adding.

I do it too, which is how I know. The impulse to put one more good thing in the bowl is hard to argue with in the moment, and I lose that argument regularly.

Decide what it's for

Before anything goes in the bowl, answer one question: what is this salad doing for the rest of the plate?

Cutting richness. Acid leads. Shaved brussels with double vinegar, a sharp slaw, pickled onions on the side. Keep the fat low and let the vinegar work.

Providing freshness. Raw, green, herbaceous. Cucumber, herbs, lettuce, lemon. Nothing cooked, nothing heavy.

Providing coolness. Temperature is the contrast. A cold salad next to hot food, and cold means genuinely cold, straight from the fridge.

Being the meal. Different rules entirely. Now it needs protein, fat and substance, and most of what follows doesn't apply.

Once you know which one it is, every ingredient either serves that job or dilutes it.

The toppings problem

Each addition seems small. Individually they all sound good. Together they turn a sharp, simple thing into a muddle where nothing is identifiable and the salad no longer does its job.

A useful discipline: pick three things beyond the leaves. Not six. Three.

Cucumber, feta, herbs. Or tomato, olives, onion. Or apple, walnut, blue cheese. Three things have a relationship with each other; six have an average.

And the harder rule: if you're adding something because it would be nice rather than because the salad needs it, that's the thing to leave out.

Don't overdress

The most common fault after too many toppings. A dressed salad should look barely dressed. The leaves glisten, they don't sit in anything, and there is no pool at the bottom of the bowl.

Dress less than you think, toss properly, taste, and add more only if it needs it. You can always add; you cannot take dressing off a leaf.

And when a salad tastes flat, the answer is usually salt rather than more dressing. Acid without salt reads as sour and thin, which people correct by adding more dressing, which makes it worse.

Match the dressing to the job

A salad meant to cut richness should not be dressed in something rich. A creamy dressing on a slaw beside pork belly is fat next to fat, and the slaw stops working.

• Cutting richness wants a vinaigrette, sharper than you would eat on its own.
• Freshness wants lemon and oil and very little else.
• Coolness can carry something creamier, since it is contrasting on temperature rather than on fat.
• Being the meal can take whatever it wants.

The test

Taste the salad next to a bite of the main, not on its own. A salad that tastes perfect alone is often too mild to register beside smoked meat, and one that tastes aggressively sharp on its own is frequently exactly right.

That is the test I trust most, and it takes ten seconds.

None of this is a rule so much as a bias. Plenty of good salads break all of it, and if you make one with eight things in it that works, it works. But when a salad lands flat next to the food it was meant to cut, the cause is usually on this page.
