French Country Salad

Start with the vinegar in the poaching water — some say it's there to flavour the egg, no, it isn't, you'd never taste two tablespoons in a pan of water. It's there because acid speeds up the setting of egg white protein, so the white firms up fast around the yolk before it has time to drift apart into strings. The vortex does the same job from a different angle: spinning water wraps the white around itself by centrifugal force. Skip both and you get a sad, feathered thing that still tastes fine and looks like a jellyfish. Your water should be at a gentle boil, not a rolling one — a hard boil just beats the egg apart before it can set, bubbles are not your friend here.

The bacon, fried first, is really there to make fat, not just itself. That fat is what you fry the bread cubes in, and later the asparagus — it's a French habit with a peasant logic: nothing in the pan is wasted, the flavour of the meat gets spread across three ingredients instead of locked into one. If you're going vegetarian and skip the bacon, use butter from the start and don't feel you've lost much — you've lost a background note, not the dish.

Potatoes boiled and halved, asparagus barely touched in the hot pan for "just a minute" — that minute is doing something specific: asparagus goes from raw-grassy to just cooked startlingly fast, and past that point it turns grey and loses its snap, so faster is the right instinct, not laziness. The green beans get the opposite treatment — into ice water the second they're out of the boil — and that's not about flavour either, it's about stopping residual heat from carrying on cooking them after you've taken them off the heat. You're chasing a colour and a bend: they should bend, not snap, and they should stay the bright green of a bean, not the khaki of an overcooked one.

Bread — any crusty, dense loaf will do, the test is whether it holds its shape as a cube in hot fat. A soft sandwich loaf collapses into greasy crumbs; you want something with a tight enough crumb to fry into a crouton rather than disintegrate. In Britain a day-old sourdough end or a baguette heel from the freezer does exactly this job, and honestly works better once it's slightly stale — stale bread has less water in it, so it crisps instead of steaming in the pan.

Olive oil in the dressing: "any oil with no smell of its own" is the wrong description for olive oil specifically, because here you want the smell — it's there to be tasted, not to disappear, so don't substitute a neutral oil and expect the same dressing. Mayonnaise and honey against the sharpness of mustard and vinegar is just balancing acid with fat and sweetness, the same arithmetic behind every vinaigrette, just with a thicker, creamier result because of the mayonnaise.

And the patience bit, because it's real here: this dish has four or five small cooking jobs that each take two minutes, and the only way to get a warm plate at the end is to have everything else — the lettuce, onion, olives, chives — already sitting arranged and waiting. If you start slicing onion while the asparagus is in the pan, the asparagus loses its minute and turns grey while you're not looking. Lay it all out before you light the hob. That's not fussiness, that's just how a dish with this many small, fast, sequential steps survives an ordinary kitchen with one hob and one pan.
