Preheat your oven to 400 degrees.

Drizzle the cut head of garlic with olive oil and place in a garlic roasted or wrap in foil. Place in the oven and roast for 40 minutes until golden and caramelize.

When the garlic has been in the oven for 20 minutes, in a heavy-bottomed skillet, add the bone pieces so they are all standing upward. Add the skillet to the over and roast for 20 minutes, until the fat is soft and melty.

Serve bone marrow hot with small spoons along with garlic, lemon, salt and toasted bread.
