Bone marrow:  Preheat your oven to 180°C or 350°F and sprinkle the bones with salt and pepper. Bake in the oven for between 10-15 minutes, just depending on the size of the bone marrow.

Onions: Cut the onions in half, but leave the skin on and roast for the same time as the bone marrow.

Vegetables: Wash the Swiss card, leeks, and other vegetables.

Prepare: Cut the white stalks out of the Swiss card and cut them up into 1-inch bits

Prepare: Peel the carrots 

Prepare: Peel the swede and cut up into quarters

Pressure Cooking: Put 50 fl oz (1.5l) water into the instant pot - and place the whole beef in - then add the carrots, swede, bay leaves, roast onions (take off skin), celery, and one of the whole leeks.

Season: Add in 10 whole peppercorns and a teaspoon of salt

Pressure Cook: For 70 minutes and 10 minutes natural release

Ice Bath: Take out the beef and carrots and swede and put them in an ice bath - this will keep the beef really moist and tender - but most of all it will stay in one piece when you cut - because in the pressure cooker it is really melt in your mouth tender beef - putting it in the ice bath lets you cut it in a slab - but when you eat it is soo good.

Clear Broth:  Take out the other vegetables and you are left with an amazing clear beef broth- season it with salt and pepper to taste.

Apples: Peel the apples - and diced them - cook them with a little bit of water in a hot pan - then eventually making them into an apple sauce. Now you can mix in the horseradish - but this is optional as people either love or hate horseradish.

Saute: Cut the remaining leeks into thin slices and saute in a little butter and oil  - about 3-5 minutes - till they just go soft. Then do the same with the Swiss chard - using a little oil and butter as well.

Chives: Finely dice some chives for finishing.

Root Vegetables: Cut the carrots and swedes into smaller nice bit sized pieces 

Beef: Cut the beef into thick slabs, about 1/2 inch - cut against the grain.

Plating Up: Now put in the clear beef broth, salt of steak, and decorate with vegetables.
