The Method
1
Bring the joint to room temperature. Season it thoroughly with salt and pepper. Place in a roasting tin and cook in a hot oven until the internal colour and surface crust indicate the desired degree of doneness. The joint is ready to leave the oven when the exterior is deeply browned and fragrant and the interior, tested by skewer or thermometer, yields the correct resistance for the chosen meat.
2
Remove the joint and rest it — minimum 20 minutes for a chicken, minimum 30 minutes for a beef or lamb joint — tented loosely with foil. This is where the dish lives or dies: cutting before the rest is complete releases the accumulated juices and produces a dry, grey interior; the full rest returns those juices to the fibre and gives the moist, pink result the Sunday roast requires. The joint should feel relaxed and slightly yielding when pressed at the end of the rest.
3
While the joint roasts, parboil the potatoes in well-salted water until the exterior is beginning to break down. Test by pressing a piece against the side of the pot — the surface should crumble. Drain, return to the pot, and shake vigorously so the surfaces become rough and broken. This abrasion maximises the surface area available to the hot fat.
4
Heat the goose fat or dripping in a roasting tin at 220 °C until smoking. Add the roughed-up potatoes to the hot fat immediately — they should sizzle on contact. Roast at 220 °C, turning once at the 30-minute mark, until the crust is deep golden and genuinely shattering when tapped with a spoon.
5
For the Yorkshire pudding batter (beef only): combine equal volumes of egg, flour, and milk-water in a bowl, season, and whisk until smooth. Rest the batter for a minimum of 30 minutes. Heat a Yorkshire pudding tin with a film of fat until smoking. Pour the batter into the smoking-hot tins and place immediately in the oven. Do not open the oven for the first 20 minutes. The puddings are done when they have risen dramatically and the walls are set and deep golden — they should be rigid and hollow-sounding when tapped.
6
Build the gravy directly in the roasting tin. Pour off excess fat, retaining the Maillard residue on the tin's base. Set the tin over heat and deglaze with the red wine or Madeira, scraping all the caramelised residue free. Add the stock and reduce until the gravy coats the back of a spoon. Taste: the gravy should be rich, savoury, and direct — it derives its depth from the drippings, not from supplementary powder or cube.
7
Carve the joint at table. Cook and serve the seasonal vegetables during the resting window so that everything arrives at the table together. Serve the carved meat with the roast potatoes, Yorkshire pudding if appropriate, vegetables, and gravy passed separately.
