Dominic Chapman recommends marinating the rib-eye steak for 24 hours to allow the herbs and mustard to penetrate the meat with flavour. Using rare-breed varieties of beef - such as Dexter or Aberdeen Angus - will make this rib-eye with mustard recipe even more luxurious.

1 hour before you cook the steak, peel and wash the potatoes. Cut into even chunks and place in a large pan, cover with cold water. Add 4 large pinches of salt and bring to a gentle boil
500g of Maris Piper potatoes
Cook until tender but still slightly firm in the centre, approximately 8-10 minutes. Drain the water and toss in the colander to gently break up edges. Leave in the colander to steam for a few minutes
Place a heavy-based roasting pan over a high heat. Add the duck fat and melt until hot. Place the potatoes in the hot duck fat and turn evenly to give each piece a crispy, golden brown finish
50g of duck fat
Transfer the potatoes to an oven set to 220°C/gas mark 8 and roast for a further 15-20 minutes. Once cooked, remove and keep warm
Turn the oven down to 200˚C/gas mark 6. Place a pan over a high heat and add a splash of vegetable oil
Add the steaks and cook until the meat is a dark brown colour, turn over and to cook the other side until a similar colour is achieved
2 240g rib-eye steaks
For a rare steak, you do not need to cook the steak further in the oven. For a medium-rare steak, place in the preheated oven for 1 minute (increase this number by 2 minute increments for medium, medium-well and well-done finishes). Remove the steaks from the oven and set aside to rest for 4 minutes. Serve with the potatoes and mustards
