Start by pre heating your oven for 450F/230C/GAS8.
Now grab your bones and a roasting tin with a bit of height. Stand the bones upright in the dish.
Tip #1: How to choose the best bones
Marrow bones can be cut to any length so ask your butcher for pieces cut from the centre of the leg bone, where the ratio of marrow to bone is highest.
The bones should be free of meat and should smell clean and faintly meaty. The marrow itself should be whitish pink in colour; don’t worry if you can see blood spots on the surface—that’s normal.
Tip #2: How to clean the bones
Sometimes the marrow is dotted with a few blood spots, it’s perfectly normal but if you want you can remove them by placing the bones in a bowl of ice water with 1 teaspoon of coarse sea salt per 250ml of water. Refrigerate for 12 to 24 hours, changing the water every 4 hours and replacing the salt each time.
Place the bones in the oven and roast for 15 to 20 minutes till the marrow has puffed a bit, its warm and the bones are brown.
Tip #3: Check its cooked
The marrow should be fully heated up so insert a metal skewer in the centre and leave it for a few seconds; if it comes out hot your marrow is cooked.
Its time to make the simplest salad ever so chop up your parsley and finely slice the shallots. Grab a bowl and mix the parsley, onion, capers with a little olive oil, lemon juice, salt and pepper.
Also, pop your bread in the toaster till its nice and crunchy, spread a bit of butter if you wish.
Serve your bones with the salad and toast and supply your guests with two little bowls of salt and pepper so they can sprinkle as they go.
Serve with chips.
Enjoy.
