Bone marrow is the soft, fatty tissue found inside the central cavities of certain bones, especially the femur and shin bones of cattle and other animals. It has a rich, buttery texture and a deep savoury flavour. In professional kitchens, marrow bones are commonly cut lengthwise (“canoe cut”) or cross-cut into rounds for roasting and other preparations.
Long bones such as the femur and tibia contain marrow within the central cavity. Canoe-cut bones are split lengthwise to expose a broad surface of marrow, while cross-cut bones produce round portions with marrow in the centre. The cut affects cooking time, presentation and ease of service.
Marrow may be soaked in cold water under refrigeration to remove excess blood, then drained and dried before cooking if the recipe calls for it. Roast until the marrow is hot and softened but not completely liquefied. It can also be poached or used to enrich sauces and forcemeats. Handle and cook it under appropriate food-safety controls.
Roasted marrow is often served in the bone with toast, herbs and an acidic garnish to balance its richness. It can be folded into a sauce, used to finish a jus or incorporated into selected stuffings and preparations. Because it is very rich, a small portion is generally sufficient.
Example: roast canoe-cut marrow bones and serve the marrow on toasted sourdough with parsley salad, capers and lemon.
French terms: os à moelle refers to marrow bones; moelle is the marrow itself.
Chef’s tip: specify the bone cut and length when ordering. Cross-cut portions and canoe-cut bones require different presentation and handling at service.
