Warm steaks to room temperature, season with salt and pepper.

Heat a heavy based frying pan, add oil and place steaks into pan. Seal and caramelise steaks on both sides. Cook in an oven at 120 C until your liking.

Rest steak after cooking, for approximately the same time as cooking time.

Mushroom pate and stuffed mushrooms:

Saute mushrooms in olive oil until lightly browned. Add onion, garlic, salt and pepper and saute until onions have softened and are translucent.

Add cream and reduce volume by about half. Blend until smooth, add parsley and blend again.

Remove stems from Swiss brown mushrooms, spoon over Madeira reduction and add salt evenly.

Bake at 180 C until mushrooms are cooked and slightly brown. Allow to cool, then fill evenly with mushroom pate, place in fridge until needed.

Re-heat at 180 C when needed for about 5 minutes.

Onion and Dark Ale puree:

Caramelise onion in grape seed oil over medium heat in a saucepan. Add dark ale, cook down until almost dry in the pan. Add vinegar, herbs and seasoning and blend until smooth, thicken with xanthan gum.

Reserve until needed.

Herb salsa verde:

Blend all ingredients until smooth in a food processor. Reserve until needed.

Truffled Hollandaise:

Warm butter to 60 C on a double boiler.

Place yolks and remaining ingredients into a second bowl. Once butter is at temperature, remove and place second bowl on the double boiler.

Whisk until fluffy and holds a ribbon. Slowly add clarified butter, whisking all the time until incorporated. Reserve warm until needed.

Housemade onion rings:

Season onion rings with salt and allow to cure for 5 minutes.

Dredge in flour, coat in batter and fry at 160 C until crisp. Reserve for plating.

Truffled Dauphin potatoes:

Melt butter in the milk, stir in flour to form a soft dough. Remove from heat and allow to cool.

Beat eggs and gradually add to cooled mix until thick, smooth and glossy to make choux pastry.

Cook potatoes, mash and pass through a sieve, then season.

Once complete, weigh 500g of finished seasoned mash, add choux pastry mix. Shape evenly with tablespoon, directly into deep fryer.

Fry at 160 C until golden and puffed, reserve until plating.

To finish and plate:

Heat a heavy based frying pan, add butter, smashed garlic and herb stalks. Add steak and baste with flavoured butter for a minute on each side.

Spread mustard on presentation side and sprinkle with chopped herbs.

Plate steak with accompaniments and serve.
