A clear broth of beef and burnt onion

A raft-clarified consommé served scalding in warmed cups, and the intellectual twin of a block of clear ice.

Pairing
Wine — A dry amontillado, served cool but not cold: the same oxidative, nutty note that goes into the raft and the finish, at a size the broth can stand next to without either one being drowned. Mixed drink — A whisky highball built hard — 1½ oz, plenty of very cold soda, a lemon peel and nothing sweet at all — because the carbonation clears the marrow fat off the palate between mouthfuls of a broth that is richer than its clarity suggests. Teetotaler — Unsweetened sour cherry juice cut half and half with cold soda and a pinch of salt, with a strip of orange peel: the sourness and slight tannin do what a red wine would do against beef, and there is no sugar in it to fight the burnt onion.

Tools
A heavy roasting tray, a dry cast-iron pan you are willing to blacken onions in, a tall narrow stockpot (tall matters — it keeps the raft in one piece), a probe thermometer, because 140, 160 and 185 to 195°F are three separate instructions and guessing them is how the raft breaks, cheesecloth and a fine sieve, a ladle with a rounded back for cutting the hole, shallow trays and a sink you can fill with cold water for the fast chill, overnight fridge space for a large volume, and cups you can warm before service

Ingredients · swaps in parentheses
Beef shin and marrow and knuckle bones (6½ lb of chicken wings and backs instead, roasted lighter, gives a paler cleaner broth with less iron), onions, carrots, celery, leek, garlic, black peppercorns, bay, parsley stalks, very lean ground beef — the leanest on the counter, since fat is exactly what the raft cannot cope with — egg whites, tomatoes or tomato purée, dry sherry for the raft and the finish, and fine sea salt, for a vegan version that is the same course rather than a concession, mixed mushrooms, dried shiitake, kombu and agar in place of the beef and the egg

Magic
While the pan is still screaming from the onions, put a lemon half cut-side down in it and let it go as dark as they did. Strain a few drops of that juice into each cup at the pour — a quarter teaspoon in ½ cup, no more. Charring pushes the juice's raw sourness back and leaves smoke and bitterness that meet the burnt onion already in the broth, so the acid reads as depth rather than as lemon, and it lifts a heavy marrow stock at the exact point in the evening where richness starts to feel like work. It costs you nothing: same pan, same minute, and the broth stays clear because you are adding drops rather than pulp. Not sold on it? Hold back the finishing sherry and add it in the cup instead of the pot, so it arrives as smell.

Before you begin
It must never boil, and that is not a stylistic preference: boiling emulsifies the fat and drives fine particles into permanent suspension, and nothing you do afterwards fully recovers it. One bubble breaking every second or two, for six hours. Stop stirring at 140°F and leave the raft alone from there — hold at 185 to 195°F with liquid rising gently through the hole you cut, and pull the heat the instant you see a rolling bubble, because a broken raft cannot be rebuilt. Cool fast and shallow: trays, a cold water bath, under 45°F within two hours, then the fridge, and throw out anything that stood warm overnight without debating it. Season only after clarification, by the quart, and taste it hot — consommé tastes markedly less salty at 185°F than at 104°F. Warm the cups 185°F broth into a cold cup in a cold room lands at about 150°F, and into a chilled one at 130°F, which is not the same dish.

Clear ice and clear broth are the same achievement bought the same way. A clear block is made by freezing water slowly and directionally, so the advancing ice front pushes dissolved air and impurities ahead of it instead of trapping them; it takes about three days. A clear broth is made by holding a stock below a simmer for hours and then lifting everything suspended out of it with a raft. Both are time made visible. Serve one in a cold room while people look at the other and nobody needs it explained.

The thing that decides whether this works is that the stock never boils. Not once, not for a minute. Boiling emulsifies fat and agitates fine particles into permanent suspension, and no amount of clarifying afterwards fully recovers a stock that has been allowed to roll. Keep it at a bare tremble — one bubble breaking every second or two — and the raft has an easy job.

Yield and timing

Yield: about 2¼ quarts of finished consommé, which is 18 servings of ½ cup. Written for 40 guests — double it.
Active: 70 minutes
Total: 2 days, most of it unattended
Make-ahead: Finished consommé holds 4 days refrigerated, 3 months frozen

Ingredients

Day one, the stock

4½ lb beef shin, cut into large pieces
2¼ lb beef marrow and knuckle bones
4 large onions, halved through the equator, skins on
2 carrots, 3 celery sticks, halved
1 head of garlic, halved across
8 black peppercorns, 2 bay leaves, a few parsley stalks
5 quarts cold water

Day two, the raft

14 oz very lean ground beef, the leanest you can buy
4 egg whites
3½ oz mixed carrot, celery and leek, finely chopped
2 tomatoes, chopped, or 2 tablespoons tomato purée
4 teaspoons dry sherry, plus more to finish
Fine sea salt, about 1½–2 teaspoons per quart at the end

Method

Roast the shin and the bones at 425°F for 40 minutes, turning once, until they are deeply browned and the tray is sticky rather than burnt.
Meanwhile, put the onion halves cut-side down in a dry heavy pan over a high heat and leave them, without moving them, until the cut faces are genuinely black — eight to twelve minutes. Not caramelized. Black. This is the burnt onion and it supplies the color and the bitterness that keeps a beef broth from tasting like gravy.
Put everything into a tall pot with the cold water, bring it slowly to a bare tremble over 40 minutes, and skim the gray foam off the top for the first 20 minutes. Then hold it there for six hours. Never let it bubble properly. Top up with hot water if the bones become exposed.
Strain through a colander and then through cheesecloth, without pressing. Cool it fast: divide it between shallow trays, stand them in cold water, and get it below 45°F within two hours. Refrigerate overnight and lift the set fat off the top in one sheet.
Next day, make the raft. Mix the ground beef, egg whites, chopped vegetables, tomato and sherry into a rough paste and stir it thoroughly into the cold, degreased stock.
Bring it up very slowly, stirring gently, until it reaches about 140°F. Then stop stirring entirely. The raft will rise and knit into a gray crust across the surface at around 160°F.
Make a hole in the raft about the size of a mug with the back of a ladle and hold the pot at 185 to 195°F for 45 minutes. Liquid should be moving gently up through the hole. If it boils, the raft breaks and you are finished; drop the heat immediately if you see a rolling bubble.
Ladle the clear liquid out through the hole, through a cheesecloth-lined sieve, without disturbing the raft. Discard the raft. Season now and not before: 1½ to 2 teaspoons of fine sea salt per quart, and a splash of sherry off the heat.
Reheat to scalding for service — 185°F in the cup — and serve in warmed cups, no garnish.

The safety line, stated once

Stock is one of the genuine food-safety items in any kitchen, because it is a large volume of nutritious liquid that cools slowly. Cool it fast and cool it shallow: divide between trays, use a cold water bath, and get it below 45°F within two hours and into a refrigerator. Reheat to a hard 185°F before serving and do not reheat more than once. These are the conservative instructions; check them against your own national food authority, and if a batch has been left standing warm overnight, throw it away without arguing with yourself about it.

Make-ahead

This is a two-day recipe and there is no shortening it. The stock is made on day one and must be refrigerated overnight in order to be degreased, which is what makes the clarification possible.

The finished consommé keeps four days refrigerated and three months frozen, and it is the single best make-ahead dish in this menu. Make it a week out, freeze it, and take it off your list.

Reheat from cold slowly and do not boil the finished broth either. It will cloud.

Holding and service

Held at 185°F in a covered pot it is stable for two hours and improves for the first thirty minutes. Beyond three hours it starts to reduce and turn salty; add a little water rather than accepting it.

Warm the cups. A ½ cup serving of 185°F liquid poured into a cold cup in a 54°F room arrives at about 150°F, which is pleasant, and into a chilled cup arrives at about 55, which is not.

At hour three it is still perfectly good, which is more than can be said for anything else on this menu.

Scaling

Scales cleanly to about 2½ gallons of stock. Beyond that the raft becomes hard to manage in a single pot, and it is more reliable to clarify in two pots than in one very large one.

The raft ingredients scale linearly with the volume of stock, not with the number of servings. The six-hour simmer does not scale at all — it is six hours for two quarts and six hours for ten.

The salt is the thing to watch. Season by the quart, at the end, after clarification, and taste it hot; consommé tastes markedly less salty at 185°F than it does at 104°F.

Substitutions that keep the idea

A vegetarian and vegan version that is genuinely the same course: a clear mushroom and burnt onion broth. Roast 2¼ lb of mixed mushrooms hard, add 3½ oz of dried shiitake, the same black onions, kombu and 4 quarts of water, simmer four hours below a tremble, then clarify with an agar raft — 2 teaspoons of agar per quart, boiled in, set, then broken and strained through cheesecloth. It is clear, dark and savory, and it is served in the same cup at the same minute.
Skip the clarification entirely: a well-made, carefully skimmed, degreased stock strained twice through cheesecloth is not clear but it is very good, and it takes an afternoon rather than two days. You lose the visual argument, which at this particular evening is most of the point, so make this call knowingly.
Chicken instead of beef: use 6½ lb of wings and backs, roast them lighter, and keep the burnt onion. Paler, cleaner, less iron. The raft is the same.

Where this belongs

This is the pivot of the evening at The Ice Was the Luxury — the course served at half past nine, ninety minutes into a cold night, that turns the temperature of the whole room. The menu concept explains why the rest of the food is hot and the ice is the only cold thing in the building.
