Fillet of Beef (Relevé)

Ingredients

Equipment Needed

• •5-quart / 4.7-litre heavy lidded roasting vessel, broiler-safe
• •Instant-read or leave-in probe thermometer
• •Slender paring knife and clean metal skewer
• •Butcher's twine
• •Fine-mesh strainer and warmed sauceboat

Instructions

1. 1

   Lard the fillet

   Chill the fatback batons until firm enough to push without bending, about 15 minutes. Working from each end of the fillet, use a slender paring knife followed by a clean metal skewer to open twelve narrow channels parallel to the grain. Push six fatback batons in from each end, staggering them so the fat runs evenly through the meat rather than collecting in its centre. If the fat softens, chill it again; forcing a warm baton only tears the beef. If one channel opens through the side, press it closed and secure it beneath the twine. Nothing is lost.

   Use fully cured, ready-to-eat fatback because the fillet is intentionally served rosy. Do not thread raw pork into meat that will remain red at the centre.
2. 2

   Tie and season

   Tie the fillet at 1 1/2-inch / 4 cm intervals so it forms an even cylinder, tightening the twine only enough to hold its shape. Season all over with the salt and leave it at cool room temperature for 30 minutes. Pat the surface dry once more, then apply the pepper. An evenly tied, dry fillet colours at the same pace from end to end; a wet or misshapen one does not.

3. 3

   Begin the poëling

   Heat the oven to 350°F / 175°C. Set up the home-scaled Poëlings (No. 250) in a heavy lidded vessel just large enough to hold the fillet, following that preparation's own entry, then place the beef inside and coat it with the prescribed butter. Cover tightly and cook for 15 minutes. Turn and baste the fillet, cover again, and continue for 8 to 15 minutes, checking early, until the centre reaches about 105°F / 41°C. Add no liquid while the meat cooks; moisture here changes poëling into braising. If the vegetable bed threatens to catch, lower the oven and move the vessel to a higher rack rather than reaching for water.

4. 4

   Colour and stop

   Uncover the vessel, baste the fillet thoroughly, and raise the oven to 450°F / 230°C. Roast uncovered for 6 to 10 minutes, turning and basting once, until the surface is a deep Maillard bronze and a thermometer inserted from the side into the true centre reads 118 to 120°F / 48 to 49°C. If the colour arrives first, shield the fillet loosely with foil and lower the heat. If the temperature arrives while the surface remains pale, lift the fillet close beneath the broiler for 30 seconds at a time, turning carefully. Do not chase colour past the temperature; overcooking this lean cut is the one failure no sauce fully repairs.

   Insert the thermometer from the side so its tip reaches the centre of the thickest section. A reading taken near the surface can send a rosy fillet back into the oven until it is grey.
5. 5

   Rest the fillet

   Transfer the fillet to a warm platter and cover it very loosely with foil. Rest for 15 to 20 minutes; the centre should rise to about 126 to 130°F / 52 to 54°C while the juices settle back through the meat. A tight foil wrapping traps moisture and softens the browned surface, so leave room for air. Pour every resting juice into the finished sauce.

6. 6

   Finish the jus

   While the beef rests, complete the cooking liquor exactly as directed in Poëlings (No. 250), including its full ten-minute contact with the butter before straining and removing the excess fat. That contact extracts the savour held by the butter; it is technique, not brigade scaffolding. The finished jus should be clear, glossy, and concentrated enough to lightly coat a spoon. If it looks greasy, let it stand for a minute and skim with a cold spoon. If it is thin, reduce it gently; if it tightens too far, loosen it teaspoon by teaspoon with warm water. Ça se rattrape.

7. 7

   Carve and serve

   Remove every length of twine and carve the fillet across the grain into slices about 1/2 inch / 1.25 cm thick. Arrange them slightly overlapping on the warm platter so the red centre and fine streaks of fatback remain visible. Spoon just enough jus over the beef to give it a gloss, then send the rest in a warm sauceboat. Serve immediately. À table!

Chef Tips

• •Ask the butcher for an evenly thick centre section, not the tapering tail. A modest fillet cooked with attention is better than a grand one that narrows to nothing and overcooks at one end.
• •The fatback must be fully cured and ready to eat without further cooking. If your butcher has only raw fatback, do not put it inside rare beef; lay thin strips over the outside beneath the twine instead, then remove them before carving.
• •Keep the thermometer beside the oven from the beginning. For this lean cut, five extra minutes can separate a red, juicy centre from a dry grey one, and the clock cannot account for the fillet's exact thickness.
• •Serve with a structured red that will not smother the delicate beef, such as a mature Médoc or a cabernet-led Bordeaux. Leftovers keep chilled for up to three days; warm thick slices briefly in the jus rather than returning the whole fillet to the oven.

Advance Preparation

• •Read and scale Poëlings (No. 250) before beginning; the timing here assumes that referenced preparation is ready for the fillet.
• •The fillet can be larded, tied, and salted up to 8 hours ahead. Keep it uncovered in the refrigerator, then let it stand at cool room temperature for 30 minutes before cooking.
• •Do not roast the fillet ahead. Its mandatory 15 to 20 minute rest gives enough time to finish the jus and gather the table without sacrificing the red centre.
