From Butcher to Table: The Koshering Process Explained

Have you ever wondered what makes kosher meat different, or what ancient wisdom lies behind the meticulous process of koshering? From biblical commandments to modern-day practices, the art of koshering meat is a fascinating blend of tradition, spirituality, and culinary science that transforms a simple cut of meat into a symbol of faith and purity.

Source of Koshering:

Koshering meat and chicken is a vital practice in Jewish dietary laws, deeply rooted in biblical commandments and long-standing traditions. The process, known as melichah (salting), is primarily based on the biblical prohibition against consuming blood, as stated in Leviticus 7:26: You shall not eat any blood, whether that of fowl or of beast, in any of your dwellings. This prohibition underscores the belief and commandment that blood represents life and should not be consumed.

The Torah provides the basis for this custom, although the exact methods of koshering were transmitted orally to Moses on Mount Sinai, as indicated by the phrase 'as I have commanded thee' in Deuteronomy 12:21. The practice involves removing as much blood as possible from the meat before it is prepared for eating, ensuring that it is fit and proper according to Jewish dietary laws.

Koshering meat involves several meticulous steps, including washing, soaking, salting, and rinsing, all performed within a specific timeframe and under strict guidelines . This process can only be applied to meat from kosher animals that have been properly slaughtered according to Jewish law (shechitah) and have passed rigorous health inspections . The lungs, for instance, must be inspected for adhesions, with different traditions (Ashkenazic and Sephardic) having specific criteria for what is considered kosher .

This comprehensive approach to food preparation reflects the Jewish tradition's emphasis on mindful eating and the sanctification of daily life through religious observance. While many families today rely on butchers for koshering, understanding the process remains an important aspect of kashrut, the body of Jewish dietary laws.

PSA:

For those interested in understanding the process of Koshering meat and chicken, this guide offers a general overview based on the Kitzur Shulchan Aruch, with some additional insights. Remember, this is only for informational purposes and is not a full guide. Consulting a Rabbi is always recommended when you are not an experienced kosherer and in specific situations.

Preparing for Kashering:

The journey to a delicious kosher meal begins with proper preparation. Assuming you had meat slaughtered (shechted) correctly. The next step is to have a certified checker to check that the animal was healthy during its lifetime and would not die within the next year from its sickness. Next the lungs are inspected to ensure they are free of adhesions or other abnormalities. Any adhesions present must be easily removable without leaving holes in the lung tissue. Lungs with such removable adhesions are still considered kosher according to Ashkanasic tradition. The sephrardic tradition is that the lungs must be smooth and free of adhesions other wise known as bet Yosef who is the the author of the opinion.  

The following is the general process of how koshering is done:

1. Cleanliness is Key: Wash the meat thoroughly in cold water to remove the external blood and to clean it. Some even recommend using a special brush for this step.
   
   
2. Soaking Away the Blood: Submerge the meat completely in clean water for about 30 minutes. During soaking, be sure to rub off any visible blood and discard the bloody water. Repeat this process for the inside of the chicken and any blood clots you may find.
   
   
3. Temperature Matters: Cold water can hinder blood removal. If the water is very chilly, warm it slightly before soaking the meat.
   
   

Cutting and Soaking:

• Fresh Cuts Need Extra Attention: After cutting a soaked piece of meat, wash the cut area thoroughly to remove any exposed blood.
• Thawing Safely: Frozen meat must be thawed before salting. Avoid using a hot oven for thawing, and in a pinch, lukewarm water can be used. For an even gentler approach, some recommend placing the frozen meat in a colander in a cool, well-ventilated area.

The Art of Salting:

• A Dedicated Vessel: Use a designated container specifically for soaking meat. This container should not be used for other foods. 
• Moisture Balance is Crucial: Drain the soaking water before salting. Too much water weakens the salt's effectiveness. However, leave some moisture on the meat to prevent the salt from falling off.
• Salt Selection: Choose a coarse medium-sized, dry salt for optimal effectiveness.  Avoid very fine or coarse salt. There's a common misconception that kosher salt is used to make meat kosher during the Kashering process. In reality, Kashering facilities typically use a much coarser salt. This is because standard kosher salt dissolves quickly, and we want to avoid the salt penetrating the meat itself. Kashering focuses on removing blood from the surface of the meat, and coarse salt sits on the surface better, drawing out the blood without being absorbed. Some companies use MORTON® TOP FLAKE EXTRA COARSE SALT.
• Thorough Coverage is Key: Spread salt generously on all sides of the meat and inside the cavity of poultry for proper salting.

Positioning for Optimal Drainage:

• Gravity's Your Friend: Place the meat on a slanted surface (not on the ground) to facilitate blood drainage during and after salting. A board with no grooves works well. When Kashering poultry or sides of beef, position the cavity downwards for better drainage. If the blood has nowhere to drain, the meat may become forbidden because the blood can reenter the meat as it sits in the blood.

Salting Time:

Time is of the Essence: Leave the meat in salt for at least one hour. In a real hurry, 24 minutes is the minimum.

After Salting:

• Rinse and Repeat: Shake off the salt completely and rinse the meat thoroughly three times with clean water known in Hebrew as Hadacha. A dedicated person should supervise rinsing to ensure proper blood removal. Never leave rinsed meat sitting in a container without water.

Poultry Specifics:

• Head Start: Remove the head of the poultry before soaking. If salted with the head on, consult a Rabbi. This applies to animal heads as well.

Separate Storage is Essential:

• Unsalted Needs Space: Store unsalted meat in a separate container that's not used for vegetables, fruits, or similar foods. Blood residue from meat can transfer to these foods if stored together and render them not kosher.

Kashering the Head:

• Open Up: Before soaking the head, split it open, remove the brain and its membrane, and soak and salt them separately. Salt the head inside and out, even with the hair on.

Bones and Organs:

• Bone Appétit: Bones with marrow can be salted with the meat if attached. If detached, salt them separately and keep them away from the meat while salting.
• Feet First: Cut off the tips of animal feet before soaking to allow blood drainage. Position them hoof-downward while salting, and you can salt them with the hair on.
• Open Heart: Open the heart before soaking to allow blood to flow out.

Lungs and Liver:

• Lungs Need Air: It's customary to open the lungs and large tubes before soaking.
• Special Treatment for Liver: Due to its high blood content, liver requires broiling over an open fire, not just salting and cooking. Before broiling, cut it open well and position the open areas on the fire for maximum blood removal. Rinse the liver before and after broiling. After broiling, rinse it thoroughly again before cooking.

Additional Liver Notes:

• Open Fire Only: Broil liver only on
