The London steakhouse plate, as Hawksmoor made famous: a thick, dry-aged bone-in rib, chips cooked three times so they shatter, and a peppery cream sauce made in the steak pan.
For the chips: 2 lb (900 g) floury potatoes (Maris Piper or russet)
About 2 quarts (2 litres) beef dripping or groundnut oil, for frying
For the sauce: 1 tbsp black peppercorns, coarsely crushed
1 shallot, finely chopped
3 tbsp brandy
1/2 cup (120 ml) beef stock
1/2 cup (120 ml) double (heavy) cream
1 tsp Dijon mustard
How to make it
Chips, first cook: peel the potatoes and cut them into thick fingers, about 3/4 inch (2 cm). Rinse in cold water. Simmer in salted water 15 to 20 minutes until they are just falling apart at the edges. Lift them out carefully onto a rack and chill them, uncovered, in the fridge for 1 hour so the rough edges dry.
Second cook: heat the dripping to 265°F (130°C) in a heavy pot (fill no more than halfway). Fry the chips in batches 5 to 7 minutes until a crust forms but they stay pale. Drain on a rack and cool.
Salt the steak all over 45 minutes before cooking and leave it at room temperature.
Heat a heavy pan over high heat until smoking, add the dripping and lay in the steak. Sear 4 minutes, turn, sear 4 minutes more, then stand it on its fat for 2 minutes. Add the butter, thyme and garlic and baste for 1 minute. For a thick rib, finish in a 400°F (200°C) oven until it reads 125°F (52°C) inside, 5 to 8 minutes. Rest 10 minutes on a rack.
Third cook: heat the dripping to 365°F (185°C) and fry the chips 2 to 4 minutes until deep golden and glassy-crisp. Drain and salt straight away.
Sauce: pour most of the fat from the steak pan, add the crushed peppercorns and shallot and cook 1 minute over medium heat. Add the brandy (careful, it may flame) and let it bubble away, then the stock; reduce by half. Add the cream and mustard and simmer 2 minutes until it coats a spoon. Season with salt.
Cut the steak off the bone, slice it thickly, and serve with the chips and the sauce on the side.
Tips
The chilling between cooks is what makes the chips glassy; don't skip it.
Leftover dripping, strained, keeps for months in the fridge.
