Method

  1. Step 1

    Heat the oven to 400°F. Stand the marrow bones cut-side up on a tray and roast for 20 minutes, until the fat is loose and trembling but not fully rendered.

  2. Step 2

    Meanwhile, cover the potatoes with cold salted water, bring to a boil, and cook until a fork slides through without resistance, about 15 minutes.

  3. Step 3

    Scoop the warm marrow out of the bones into the pot with the drained potatoes. Add the butter and a splash of warm milk.

  4. Step 4

    Mash everything together while hot. The marrow melts into the potatoes and disappears completely. Add more milk until the texture is loose and glossy.

  5. Step 5

    Salt it harder than you think it needs. Marrow fat is rich enough that undersalted mash reads as flat. Serve under any steak.
