Horse-radish Sauce

Ingredients

Equipment Needed

• •3-quart nonreactive mixing bowl
• •Food processor fitted with a fine grating disc, or a sturdy fine box grater
• •Fine-mesh sieve or clean kitchen towel
• •Chilled sauceboat

Instructions

1. 1

   Soak the crumb

   Put the fresh white breadcrumbs in a wide bowl and pour over the milk. Turn them gently until every crumb is saturated, then leave them for 10 minutes. Gather the softened crumb in a clean towel or press it firmly through a fine-mesh sieve until a squeezed handful remains soft but releases no stream of milk. Reserve ¼ cup of the soaking milk in the cold for adjusting the finished sauce, then discard the rest.

   Use the soft inner crumb of an unsweetened white loaf, not dry packaged breadcrumbs. Dry crumbs drink the cream unevenly and leave the sauce sandy.
2. 2

   Make the acid base

   Whisk the Dijon mustard and white wine vinegar together in a chilled, nonreactive bowl until completely smooth. Make this base before grating the horseradish. Once the root is cut, its volatile bite begins changing quickly, and the acid must be waiting for it.

3. 3

   Rasp the raifort

   Finely rasp the peeled horseradish with a sturdy grater or the fine grating disc of a food processor. Work near an open window and keep your face away from the feed tube, because fresh horseradish is vigorous company. Immediately scrape the rasped root into the mustard-vinegar base, then add the powdered sugar and salt. Fold until every strand is coated and the mixture smells clean, sharp, and mustardy.

   Do not replace the fresh root with prepared horseradish. The jar already contains vinegar and salt, which would upset the book's measured balance and give a softer bite.
4. 4

   Bind with cream

   Pour in the cold cream and stir gently until the sharp horseradish mixture turns pale ivory. Crumble in the pressed breadcrumbs a handful at a time, folding after each addition so they disperse without forming lumps. Add all the crumb, then fold just until the sauce is thick, coarse, and spoonable. Do not purée it smooth. The rasped texture and milk-softened crumb are the dish, not an inconvenience to be processed away.

5. 5

   Chill it hard

   Cover the bowl tightly and refrigerate for at least 2 hours. The sauce will firm as the crumb finishes binding the cream, while the cold keeps the horseradish bite alive. Stir once from the bottom before judging it. If it has set too stiff to fall heavily from a spoon, ça se rattrape: fold in the reserved soaking milk 1 teaspoon at a time until it loosens. If it seems loose, return it to the cold for another 30 minutes before changing anything.

6. 6

   Serve very cold

   Taste the thoroughly chilled sauce and correct the salt only now, because cold softens seasoning. Spoon it generously into a chilled sauceboat and return the remainder to the refrigerator between servings. Serve it very cold with boiled beef or a roasted joint, exactly where its cream, sweetness, and sharp root can cut through rich meat. À table!

Chef Tips

• •Choose a fresh horseradish root that feels hard and heavy, with no soft patches or shriveled ends. A tired root gives plenty of fiber and very little fire, and cream cannot restore what the market has already lost.
• •The book says rasped, and that matters. A fine grating disc saves the saucier's arm without changing the result; a chopping blade turns the root into wet paste and drives away much of its character.
• •This is a generous holiday quantity because the sauce was built to accompany a whole joint. For a smaller table, halve every measured ingredient exactly, including the mustard and vinegar. C'est la même grammaire.
• •Serve the sauce from the refrigerator, not after an hour on the table. Chill is what keeps the bite clean, and the contrast between cold sauce and rich beef is part of the pleasure.
• •Keep leftovers tightly covered and refrigerated for up to 2 days. The sauce remains safe after that if handled properly, but the horseradish steadily loses its nerve. Do not freeze it; the cream and pressed crumb separate on thawing.

Advance Preparation

• •Prepare the complete sauce at least 2 hours and up to 24 hours before serving. Keep it tightly covered so the fresh horseradish remains bright and the cream does not absorb refrigerator odors.
• •The breadcrumbs may be soaked, pressed, covered, and refrigerated several hours ahead. Grate the horseradish only when the mustard-vinegar base is ready, because that final rasping should never wait.
