Blanch and Skim the Beef
15 Mins
Boiling water, 100°C (212°F)
Put the beef and marrow bones in the largest pot you own and cover with cold water. Bring slowly to a boil, skimming off the grey foam as it rises, for about 15 minutes. Drain, rinse the pot and the meat, and start again with fresh cold water — this second start is what makes the broth clear.
Starting from cold water, twice, is the old trick for a crystal-clear bouillon — never skip the blanch.
Done when: The water runs clear and no more foam rises.

Simmer the Beef and Broth
150 Mins
Gentle simmer, about 95°C (203°F)
Return the beef and bones to the clean pot with the onion, celery and half the salt. Cover with cold water, bring slowly to the gentlest simmer, and skim whenever foam appears. Cover partly and simmer for 2 hours and 30 minutes, skimming the fat from time to time.
If the surface is jumping, the heat is too high — the pot should barely tremble.
Done when: The broth is clear and golden, and the beef yields easily to a fork.

Add the Vegetables in Stages
60 Mins
Gentle simmer, about 95°C (203°F)
Lift out the beef and keep it warm under foil. Add the carrots, leeks, turnips and the rest of the salt to the pot and simmer for 30 minutes. Then add the potatoes and cabbage wedges and simmer for a further 30 minutes until everything is tender.
Vegetables go in late and in order — roots first, potatoes and cabbage last — or they dissolve.
Done when: The vegetables are tender when pierced with a knife but still hold their shape.

Rest, Carve and Strain
15 Mins
Simmering broth, about 95°C (203°F)
Return the beef to the pot for 10 minutes to heat through. Lift it out, untie it and slice it thickly across the grain. Strain the broth through a fine sieve and season with the remaining salt.
Slice the beef thick — thin slices dry out in the time it takes to reach the table.
Done when: The beef slices cleanly and the strained broth is clear and golden.

Serve in Two Courses
10 Mins
Serve hot, above 74°C (165°F)
Serve the hot broth first, in bowls, with bread. Then set the sliced beef, marrow bones and vegetables on a platter, with the Dijon mustard, cornichons and coarse salt passed at the table. Spread the marrow on toast if you like.
Do not salt the whole pot at the end — let everyone season their own plate.
Done when: The broth is steaming, the meat is hot through, and the table is set with mustard and cornichons.

Serve the broth first, in bowls, then the carved beef and vegetables on a platter with Dijon mustard, cornichons and coarse salt — two courses from one pot.
