Chullin 93

Hook

Imagine the sensory symphony of a Jewish quarter in medieval Fes or early-modern Damascus on a Thursday morning. Above the calls of vendors selling cardamom, mint, and fresh figs, there is a rhythmic, focused sound: the scraping of knives against marble blocks in the kosher butcher shops. Here, the menaker—the master of ritual porging—practices an ancient, highly specialized art. With fingers as sensitive as a surgeon’s and a gaze as sharp as the steel in his hand, he traces the delicate, winding pathways of nerves and fats inside the animal's hindquarters. This is not merely food preparation; it is a sacred dance of dissection, a living chain of physical and spiritual translation. It is the physical manifestation of the Talmudic discourse in tractate Chullin, where the boundaries between the holy and the mundane, the permitted and the forbidden, are carved directly into the flesh of the physical world.

Context

To fully appreciate the depth of this practice, we must ground ourselves in the historical soil from which this sacred anatomy emerged:

• Place: The bustling urban centers of the Sephardic and Mizrahi world—from the sun-drenched courtyards of al-Andalus (Islamic Spain) to the ancient, winding alleys of North Africa and the Levant.
• Era: The golden eras of halakhic codification (the 11th through the 14th centuries), a time when the legal genius of the Geonim of Babylonia was synthesized by the towering scholars of the Mediterranean basin.
• Community: The tightly knit guilds of Jewish butchers (qasabim or tabachim) and ritual slaughterers (shochetim). These craftsmen were not isolated laborers but respected communal leaders, working in close tandem with local rabbinical courts to maintain a continuous, unbroken chain of anatomical transmission.

Text Snapshot

The Talmud in Chullin 93a wrestles with the intricate mapping of forbidden fats (chelev) and blood vessels that must be removed before meat can be eaten:

"Rabbi Abba said that Rav Yehuda said that Shmuel said: The fat that is covered by the flesh is permitted... Rabbi Yoḥanan said: I am not a butcher and I am not the son of a butcher, but I remember that this is what they would say in the study hall: When an animal is alive its limbs separate at the joints as it walks, so that the fat under the loins is exposed." Chullin 93a

The Anatomy of the Living Animal

In this passage, the Talmudic sages grapple with the dynamic nature of the animal body. They recognize that an animal is not a static specimen but a living, breathing creature whose muscles shift, stretch, and contract. The definition of "covered fat" (chelev shehabasar chofeh oto) cannot be determined solely by looking at a motionless carcass on a butcher's hook. Instead, the sages analyze the movement of the joints during the animal's life. This dynamic understanding of anatomy is a hallmark of the Talmudic approach to physical reality: the physical state of the world is defined by its active, living functions.

The Humility of Rabbi Yohanan

There is profound beauty in the statement of Rabbi Yohanan: "I am not a butcher and I am not the son of a butcher." Here, one of the greatest sages of the Land of Israel acknowledges the limits of his own academic knowledge. He recognizes that the practical, hands-on expertise of the craftsmen—the butchers who handle the meat daily—holds its own form of Torah authority. The "study hall" of Jewish law is not a closed ivory tower; it is a space that actively listens to, respects, and integrates the lived experience of the working community.

The Halakhic Synthesis of the Rif and Rambam

This passage serves as a foundational text for the great Sephardic codifiers. When the Talmud discusses the fat of the kidneys and the loins, it sets off a chain of legal interpretation that spans centuries. Sages like Rabbi Yitzhak Alfasi (the Rif) and Rabbi Moshe ben Maimon (Maimonides, the Rambam) took these raw Talmudic debates and transformed them into clear, practical guidelines for their communities, balancing the strict boundaries of Torah law with a deep-seated desire to avoid placing unnecessary burdens on the daily lives of the people.

The Art and Lineage of Nikkur (Porging)

In the Sephardic and Mizrahi heritage, the process of nikkur (known in Yiddish as treiberen—the removal of forbidden fats, veins, and the sciatic nerve) is treated as a highly esteemed discipline, almost akin to the writing of a Torah scroll. A master menaker (porger) was required to undergo years of rigorous apprenticeship. This was not a skill that could be learned simply by reading a book; it required a tactile, hands-on transmission of knowledge.

The menaker had to learn the difference between shuman (permitted fat, which is often rich, buttery, and integrated into the muscle fibers) and chelev (forbidden fat, which tends to form as a distinct, peelable membrane over the organs). In Chullin 93a, the Gemara details the various membranes of the spleen, kidneys, and testicles, distinguishing between those forbidden by Torah law—under pain of karet (spiritual excision)—and those forbidden by rabbinic decree.

In the Sephardic tradition, this delicate work was guided by the halakhic rulings of the Rif Rif Chullin 30b:1 and the Rambam Mishneh Torah, Forbidden Foods 7:7. For instance, regarding the white fat of the kidney (loben hakolya), a famous dispute arose between the early authorities. While some sages ruled stringently, requiring the deep and arduous gouging of the kidney to remove every vestige of white tissue, the Rif and the Rambam ruled more leniently, in accordance with the Talmudic sage Rav Assi. They held that only the easily accessible, superficial fat needed to be peeled away (gaim leh), as the inner white tissue was not classified as the forbidden chelev of the kidneys.

The Rashba, Rabbi Shlomo ben Aderet of Barcelona, defended this lenient ruling in his commentary, noting that "the fat that is covered by the flesh is permitted" is an established halakhic principle Rashba on Chullin 92b:8. This pragmatic, anatomically precise approach is characteristic of the Sephardic legal tradition: a commitment to absolute accuracy without adding unnecessary stringencies that would lead to the wasteful discarding of kosher food.

The Soundscape of the Meat Market: Piyutim and Communal Trust

This meticulous labor of nikkur did not take place in silence. In the Jewish quarters of Morocco, Turkey, and Yemen, the rhythms of the butcher shop were deeply intertwined with the musical and spiritual life of the community. Many of the butchers and ritual slaughterers were themselves accomplished chazzanim (cantors) and masters of the maqam (the Middle Eastern system of melodic modes).

As they worked to prepare the meat for the holy Shabbat, it was common for these craftsmen to hum or sing piyutim (liturgical poems). In the Moroccan tradition, during the preparation of the meat on Thursday nights and Friday mornings, butchers would sing portions of the Shir HaShirim (Song of Songs) or local paraliturgical songs of praise. The rhythmic scraping of the knives became a percussion accompaniment to melodies of devotion.

One beautiful connection lies in the Moroccan baqashot (nightly petitions sung in the early hours of Shabbat morning during the winter months). The singers, who had spent their week engaged in physical labor—including the butchers who had worked tirelessly to prepare the community's meat—would gather in the synagogue. Their voices, raw from the cold and the dust of the market, would rise in exquisite, complex melodies, transforming their physical exhaustion into spiritual ecstasy.

The same hands that had carefully traced the sciatic nerve (gid hanasheh) Genesis 32:33 on Thursday were raised in prayer on Saturday, clapping to the rhythms of Andalusian classical music. This integration of the physical and the spiritual is central to the Sephardic worldview: there is no separation between the holy work of the synagogue and the holy work of the marketplace. Both are arenas for the service of the Creator.

The Social Fabric of the Mellah and the Mahallah

The trust reposed in the menaker was absolute, yet it was also supported by a robust system of communal oversight. In the mellahs (Jewish quarters) of Morocco and the mahallahs of Yemen, the local rabbi would make unannounced visits to the butcher shops, not out of suspicion, but to participate in the shared responsibility of feeding the community.

The butchers themselves took immense pride in their lineage. A family of menakerim in Baghdad or Aleppo would guard their specific techniques of nerve-extraction as a sacred family heirloom, passing the secrets of the craft from grandfather to father to son. This pride was not arrogant; it was a deep, humbling awareness that the spiritual well-being of the entire community rested on the tip of their knives. If a butcher made a mistake, he could inadvertently cause his neighbors to transgress some of the most serious dietary prohibitions in the Torah. Thus, the butcher shop was not just a commercial enterprise, but a sacred trust, a sanctuary of daily mindfulness.

The Hindquarter Debate: Sephardic Precision vs. Ashkenazic Communal Realities

To understand the unique flavor of the Sephardic and Mizrahi approach to the laws of kosher meat, it is illuminating to examine how different Jewish sub-cultures historical approached the anatomy of the animal's hindquarters. This comparison reveals how geographical, economic, and social factors shaped the development of halakhic practice, without elevating one tradition over another.

In the Torah, the consumption of the sciatic nerve (gid hanasheh) is strictly prohibited:

"Therefore the children of Israel do not eat the sinew of the hip which is on the hollow of the thigh, unto this day..." Genesis 32:33

Additionally, much of the highly prohibited chelev (forbidden fat) is located in the posterior section of the animal, around the flanks, loins, and kidneys Leviticus 3:4. To make the hindquarters of an animal kosher, a highly intensive, meticulous process of nikkur (porging) must be performed. Every trace of these forbidden nerves, blood vessels, and fats must be completely extracted.

The Sephardic Practice of Hindquarter Porging

In the Sephardic and Mizrahi world—including the communities of Israel, Syria, Turkey, Greece, Morocco, and Yemen—the practice of performing nikkur on the hindquarters (Nikkur Ha’achorayim) was maintained continuously throughout the centuries. Because these communities were often concentrated in large, stable urban centers with highly organized communal structures, they were able to maintain a continuous, unbroken chain of training for master menakerim.

As a result, Sephardic Jews have historically enjoyed cuts of meat derived from the hindquarters, such as sirloin, tenderloin, and rump steak, prepared with exquisite care and absolute halakhic integrity. The master menaker in these communities would spend hours patiently dissecting the hindquarter of a steer, pulling out the complex network of the sciatic nerve—which, as the Gemara in Chullin 93a notes, splits into multiple branches on the right and left sides—and scraping away the forbidden fats with surgical precision.

The Ashkenazic Custom of "Non-Porging"

In contrast, in the Ashkenazic communities of Central and Eastern Europe, a different communal reality led to a very different practice. Ashkenazic Jews historically lived in more scattered, rural, and economically precarious settings. In many small European shtetls, there was simply no one available who possessed the highly advanced, specialized training required to perform the complex and time-consuming process of hindquarter nikkur.

Furthermore, if a menaker made even a slight error in removing the deeply embedded forbidden fats, the consumer would be liable to the severe spiritual penalty of karet. Fearing that the lack of highly trained experts would lead to accidental transgressions, Ashkenazic rabbinic authorities gradually instituted a widespread custom to simply avoid using the hindquarters of kosher-slaughtered animals altogether. Instead, the entire back half of the animal was sold to non-Jewish butchers.

This difference in practice is not a matter of one community being "more kosher" or "more holy" than the other. Rather, it represents two beautiful, distinct paths of religious devotion:

Feature	Sephardic / Mizrahi Practice	Ashkenazic Practice
Primary Approach	Halakhic Mastery and Continuity: Preserving a highly complex, ancient physical craft through rigorous apprenticeship, allowing the elevation of the entire animal.	Communal Protection and Caution: Establishing a protective fence around the law to prevent accidental transgressions in the absence of widespread expert training.
Anatomical Scope	Consumes both forequarters and meticulously porged hindquarters.	Consumes only the forequarters (up to the twelfth rib); hindquarters are sold.
Socio-Cultural Driver	Stable, urban guild structures that allowed for the continuous, multi-generational transmission of specialized anatomical knowledge.	Scattered, rural demographics where maintaining highly specialized anatomical experts in every small community was unsustainable.

Both approaches are deeply moving expressions of love for the Torah. The Ashkenazic custom shows a profound willingness to make financial sacrifices and forgo prime cuts of meat to ensure that not even a single thread of a forbidden nerve is consumed. The Sephardic custom shows a beautiful, courageous commitment to mastering the physical world, refusing to let an ancient, holy craft slip into forgetfulness, and asserting that through patience, knowledge, and skill, even the most complex parts of physical creation can be elevated and sanctified.

Home Practice

While the physical practice of nikkur is a highly specialized craft that should only be performed by certified experts, the spiritual and culinary values that underpin this Sephardic tradition are accessible to everyone. Here is one beautiful, practical way to bring the flavor of this heritage into your own home:

Mindful Culinary Elevation (The Sephardic Table)

The next time you prepare a meal, turn the preparation of your food into an act of conscious connection. In the Sephardic tradition, the kitchen table is viewed as an extension of the altar (mizbe'ach) in the Temple.

• Anatomical Mindfulness: Before you cook a piece of meat or prepare vegetables, take a moment to look at the food with wonder. Notice the patterns of the fibers, the marbling of the fat, the intricate design of the veins in a leaf of kale. Reflect on the incredible complexity of the physical world.
• The Power of Intentional Preparation: As you trim away excess fat, wash away dirt, or peel away outer skins, do so with the conscious intention of separating the "peel" (klipah) from the "essence" (pri). This simple act of sorting and refining is the spiritual root of nikkur—the active process of choosing what to elevate and what to release.
• A Song of Gratitude: Elevate your kitchen by playing or humming a traditional Sephardic pizmon (table song) or piyut while you cook. By filling your kitchen with holy melodies, you transform the physical act of cooking into a spiritual liturgy.

By bringing this level of mindfulness and song into your kitchen, you connect directly to the legacy of the menakerim of old, who understood that holiness is not found by escaping the physical world, but by entering into its deepest, most intricate details with love, reverence, and song.

Takeaway

The intricate discussions in tractate Chullin regarding the hidden fats and winding nerves of an animal are not dry, ancient history. In the Sephardic and Mizrahi heritage, these laws are a vibrant testament to a profound spiritual truth: the Divine presence is found in the details. By maintaining the continuous, living tradition of nikkur, our ancestors demonstrated that the physical world is not an obstacle to spirituality, but the very canvas upon which it is painted.

Through the combination of surgical precision, halakhic courage, and musical devotion, the Sephardic tradition reminds us that even the most mundane, physical aspects of our lives—the food we eat, the knives we hold, the markets we walk through—can be transformed into a song of praise to the Creator. May we carry this legacy of mindfulness, joy, and physical elevation into our own lives, finding the holy sparks hidden within the very fabric of our everyday worlds.
