  2. 2Sear and rest lamb15 min

    Sear the lamb racks hard in neutral oil to develop colour, then rest 15 minutes before crusting.

    The resting step after searing is the key to even pink throughout — don't skip it.

  3. 3Crust and roast lamb

    Brush lamb with Dijon mustard, press on the herb crust, and roast at 100°C until internal temperature reaches 50°C.

    Low and slow roasting keeps the meat pink edge to edge with no grey ring.

  7. 7Finish the jus

    Off heat, whisk ice-cold butter cubes into the jus for a mirror-gloss shine (monter au beurre).

    The cold butter must be added off heat and whisked in gently to emulsify properly.
