Barley With Slow Leeks and Brown Butter, Which Will Wait for You

The starch that holds for an hour and gets better doing it — cooked like a risotto or in a tray in the oven, depending on how many people are coming.

Pairing
Wine — A Jura chardonnay, or anything with that faintly oxidative nuttiness — it meets brown butter on its own ground while staying dry enough not to make the bowl feel heavier. Mixed drink — A dry cider highball built from the bottle already open for the pan — over plenty of ice, a wide strip of lemon peel, a dash of bitters, and no sugar at all. Teetotaler — Cold pressed pear juice with a hard grinding of black pepper over the surface and enough lemon to stop it reading as syrup — pear and pepper is the same conversation the barley and the butter are already having.

Tools
A wide pan with a lid for the leeks, a dry heavy pan for toasting the grain, and — the one piece that actually decides the dish — a small pale-bottomed pan for the butter, because you are reading the colour of the milk solids and a dark or deep pan hides them until it is too late, which is also why the butter will not brown more than about 400 g at a time. Then a ladle and hot stock kept hot, a tray to spread par-cooked barley on if you are working ahead, a microplane for the zest, deep roasting trays and foil if you have gone over to the oven method, and a wide serving dish under fifteen centimetres tall so it does not shadow the face opposite

Ingredients · swaps in parentheses
Pearl barley (farro and spelt both work and land firmer and nuttier — pearled farro in about 30 minutes, whole spelt in an hour with an overnight soak — though neither waits as forgivingly, which is the whole reason barley is first choice, toasted buckwheat groats are the closest gluten-free thing in character but must be served within half an hour of cooking, and short-grain brown rice holds better and tastes duller, so say which one you have made rather than passing either off as the dish), chicken or vegetable stock that has been tasted for salt before it goes anywhere near the grain, leeks, an onion, a great deal of unsalted butter (olive oil is not a swap so much as a different plan — fry fine breadcrumbs in it until deep gold and stir those through instead, losing the dairy and gaining crunch), dry cider or white wine, thyme, fine and flaky sea salt, far more coarsely cracked black pepper than seems sensible, a lemon, and a hard sheep's or cow's cheese if you want it

Magic
Pour a third of the brown butter into a small shallow dish while it is still hot, stir in the lemon zest and a good half of the cracked pepper, and put it in the fridge to set hard. That block goes to the table with a fine grater, and gets grated over each bowl as it is served. Brown butter is an aroma before it is a fat, and an aroma stirred into a warm tray at seven o'clock is largely gone by half past eight — which is exactly the hour this dish is designed to sit through. Cold shards melting into hot grain release the toast-and-hazelnut smell at the nose instead of in the pan, and the zest and pepper arrive raw rather than stewed, so the last bowl out smells like the first one. If grating something at the table is a step too far, keep that third back in its jar instead and spoon it over the top just before it goes out, rather than stirring every gram of it through at the start.

Before you begin
Season the stock properly before it meets the grain and taste it as you would a soup, because barley takes its seasoning from the liquid and cannot be fixed at the end. Wash the leeks like you mean it — grit in a soft dish is unrecoverable — and keep them pale, since the browning in this dish belongs to the butter. Add stock in stages and stir only occasionally barley is not a risotto and does not need coaxing, but it drinks more than you expect. Pull it about two minutes before you think it is ready, because it keeps cooking and keeps absorbing on the side. The butter is the moment that goes from right to wrong in seconds: it melts, foams, goes quiet, and the solids run cream to gold to hazelnut, and you pour it out of the pan the instant it smells of nuts, solids and all, or residual heat takes it to burnt in another twenty seconds. Hold the butter and the cheese back until the barley is going out, since both go dull and faintly waxy after an hour in a warm tray. It thickens as it stands — a ladle of hot stock at the forty-minute mark brings it straight back — but by hour two it is stodgy and no amount of stock fixes the texture.

Potatoes were the obvious answer for this dinner and they are the wrong one, because potatoes need a window and this evening does not have windows. Barley needs nothing. It sits warm for an hour, thickens slightly, loosens again with a ladle of stock, and tastes better at the end of that hour than it did at the start.

The thing that decides whether it is good is the brown butter, and specifically whether you take it far enough. Butter that has merely melted and gone slightly golden does nothing. Butter cooked until the milk solids at the bottom are the color of a hazelnut skin and the whole pan smells of toast is a different ingredient, and it is the difference between a bowl of grain and something people go back for.

Two methods below. The stovetop one is better. The oven one is the one you will use if more than thirty people are coming.

Yield

Serves 10 as a side alongside a braise. Written for the 20-guest version of this evening as two pans, or one tray of the oven method.

Time

Active: 45 minutes on the stovetop, 20 minutes for the oven method. Total: 1 hour 15. Make-ahead window: leeks and brown butter three days; the barley itself up to six hours ahead, undercooked slightly and finished at service.

Ingredients

1 lb 2 oz pearl barley (about 2½ cups)
1¾ quarts chicken or vegetable stock, kept hot, and tasted for salt before it goes anywhere near the grain — barley absorbs seasoning from the liquid and cannot be rescued at the end
1 lb 5 oz leeks (about 4 medium), white and pale green, halved lengthways, washed properly and sliced ¼ inch thick
1 onion (5 oz), diced small
4 tablespoons unsalted butter, for the leeks
1 stick unsalted butter, for browning
⅔ cup dry cider or white wine
8 sprigs thyme, leaves picked
1 tsp fine sea salt for the leeks, plus more for the stock, plus flaky salt to finish
1½ tbsp coarsely cracked black pepper (a great deal, and the dish is built around it)
Zest of 1 lemon
½ cup hard sheep’s or cow’s cheese, finely grated (optional; leave it out for the vegan version and add 1½ tablespoons more brown butter’s worth of oil instead)

Method — the stovetop version

Melt the 4 tablespoons of butter in a wide pan, add the leeks, the onion and the fine salt, cover, and cook over a low heat for 20 to 25 minutes. Stir every five minutes. They are done when they have collapsed to about a third of their volume, taste sweet, and have no squeak left in them. Do not brown them; this is the soft half of the dish.
Meanwhile, toast the barley in a dry heavy pan for 4 to 5 minutes, shaking, until it smells nutty and a few grains have gone a shade darker. This is worth doing and takes no time.
Tip the toasted barley in with the leeks, stir for a minute, then add the cider and let it bubble away almost completely.
Add the hot stock about 1¼ cups at a time, stirring occasionally — not constantly, this is not a risotto and barley does not need coaxing. Keep it at a gentle simmer. It takes 35 to 45 minutes and drinks more liquid than you expect.
It is ready when the grains are tender with a slight bite at the center and the whole thing is loose and creamy rather than dry — pull it about two minutes before you think, because it keeps cooking and keeps absorbing.
Meanwhile, brown the stick of butter in a small pale-bottomed pan over medium heat. It melts, foams, goes quiet, and then the solids on the base turn from cream to gold to hazelnut. The smell moves from dairy to toast to nuts. Pull it at nuts, and pour it out of the pan immediately, solids and all, or the residual heat takes it to burnt in another twenty seconds.
Stir the brown butter, thyme, black pepper, lemon zest and cheese through the barley. Taste. It will want more salt than feels reasonable and considerably more pepper.

Method — the oven version, for more than thirty people

Cook the leeks as above, in whatever quantity, up to three days ahead. On the day: combine the toasted barley, the cooked leeks and the hot stock in deep roasting trays, at a ratio of 1 part barley to 3 parts stock by volume. Cover tightly with foil. Bake at 325°F for 50 to 60 minutes, stirring once at the halfway point, until the grain is tender and most of the liquid is gone.

Finish with the brown butter, pepper, thyme, zest and cheese as above, stirred through in the tray. It is very slightly less creamy than the stovetop version, and nobody at a table of a hundred and fifty has ever noticed.

Make-ahead

Three days out: the leeks, cooked and refrigerated. They improve. The day before: the brown butter, made and kept in a jar at room temperature; it re-melts in seconds. Up to six hours ahead: cook the barley to about 80% — tender outside, distinctly firm at the center — spread it on a tray to stop it cooking, and finish it at service with the last 1¼ cups of hot stock and the butter.

What must not be done ahead: adding the brown butter and the cheese before the barley is going out. Both go dull and slightly waxy if they sit in a warm tray for an hour.

Holding and service

This is the best-holding dish on the menu after the braise. It sits happily covered in a low oven or over a bain-marie for a full hour and improves slightly as the flavors settle. It thickens as it stands — at the forty-minute mark, stir through a ladle of hot stock and it comes straight back.

At hour two it has gone stodgy and no amount of stock quite fixes the texture, though it still tastes good. That is the point at which it stops being worth putting out fresh.

It can be plated in advance and will not suffer for twenty minutes, which the cabbage cannot. Serve it in a wide low dish, under six inches tall, for the same reason as everything else at this table: anything taller shadows the face opposite.

Scaling

The barley, the leeks, the butter and the aromatics all multiply exactly. The stock does not: a deeper pan or tray evaporates less, so above about 4½ lb of barley reduce the stock ratio from 1:3.2 to about 1:2.8 by volume and add more if it needs it. Adding is easy; taking out is not.

The method changes at 30 covers, where the stovetop version becomes an hour of somebody stirring a pan they cannot leave. Switch to the oven method and do not feel bad about it.

The brown butter does not scale past about 14 oz in one pan, because a deep pan hides the color of the solids and you cannot read it. Brown it in batches.

Substitutions

Farro or spelt for the barley. Both work and both are firmer and nuttier. Pearled farro takes about 30 minutes rather than 40; whole spelt takes an hour and needs an overnight soak. Neither holds quite as forgivingly as barley does, which is the one reason barley is first choice here.

Buckwheat or short-grain brown rice, for a gluten-free version. Barley contains gluten and there is no way around that. Toasted buckwheat groats are the closest thing in character — nutty, savory, quick, 15 minutes — but they hold far less well and should be cooked within thirty minutes of service. Brown rice holds better and tastes less interesting. Say which one you have made rather than presenting either as the same dish.

Olive oil for the brown butter, in a vegan version. Not equivalent — brown butter is the whole point of the dish and oil cannot do what it does. Get closer by frying ¾ cup fine breadcrumbs in a scant ½ cup of good olive oil until deep gold, then stirring those through at the end. You lose the dairy and gain a crunch, which is a fair trade rather than a pretence.

Why this is here

Barley is the starch for One Match, an evening on Tangled Thistle where a room starts in total darkness and lights itself over eleven minutes from a single flame. It is here for a practical reason and a second, quieter one. The practical reason is that the kitchen at that dinner is working to a clock set by a candle rather than by a chef, and barley does not mind waiting. The quieter one is that barley, tallow, beeswax and a cold hall all belong to the same world without anybody having to explain the connection — and the zero-proof drink on the same table is built on toasted barley too. The full design is Everything Is Already on the Table.
