What is Bone Marrow?

The supple, fatty tissue found inside a bone is called bone marrow. The Marrow from the inside typically serves as a whole bone split in half.

While many restaurants have recently started serving bone marrow as an appetizer, eating the Marrow inside the bones of animals such as lions dates back to prehistoric times.

How to Prepare the Bone Marrow?

All bones contain Marrow, but not all can be used to prepare this dish. Ideally, you should locate a particular huge marrow bone (e.g., not soup bones). Ask for a lovely chunk of bone marrow from your neighborhood butcher, and ask them to chop it for you lengthwise.

There must be some planning done before you begin cooking.

1. Pre-soak the bones for one day.
To get rid of any blood spots and bacteria, place the bone marrow in salted water and refrigerate it for at least 24 hours as much of that blood as possible is “bleached” out during this process, which also tightens up the Marrow.

You’ll see how clean it is the next day. The more time you give it, the more blood the bones lose.

2. Scrub the skeleton
Remove other flesh from the bones before cooking if your presentation is important.

To accomplish this, take your least favorite knife—one you won’t worry about breaking—and, using the back of the blade, scrape off any meat that is still adhered to the bones. If you’ve given the bones enough time to soak, they should easily peel off. Chop any remaining meat bits with a knife if you cannot scrap them.

3 Tips for Freezing Bone Marrow

Now that you know how to freeze it, here are our top three recommendations for getting the best results from bone marrow freezing:

  • Use a Lid That Fits Tightly.
    It’s crucial to seal the container the bone marrow you’re working with is in so that the smell from the bone marrow itself won’t permeate your freezer and give your other ingredients different tastes and smells. Make sure the container is tightly sealed to prevent adding to freezer odors.
  • Hold the temperature steady.
    Because bone marrow is mostly fat, maintaining a constant temperature is essential because it will eventually start to go bad. This could happen due to frequent thawing and freezing because heat is more closely related to fat going rancid than bacterial growth.
  • Squash It Without Fear
    It’s a good idea to press the bone marrow down in your container so that it is compressed to fit the area you have available because it is normally thick yet compressible. This makes it possible to use your freezer more efficiently by packing a surprising amount of bone marrow into a single container.


Collagen, conjugated linoleic acid, glycine, and glucosamine are health-promoting substances in the bone marrow. Even though there is little information on the health advantages of bone marrow, these substances have been associated with reduced inflammation, better skin health, and enhanced joint function. The best part is that bone marrow is readily accessible, delectable, and simple to use in several dishes.
