The Fattest Cut: Pork Belly
Unsurprisingly, the pork belly is the fattiest cut of the pig, taken from the animal's underside. This boneless cut is composed of alternating layers of rich, creamy fat and lean muscle. Its fat content can vary widely, but research shows it can be anywhere from 20% to over 60% fat, depending on the animal and specific section. It is this significant fat-to-meat ratio that makes it so flavorful and succulent. When cured and smoked, pork belly becomes bacon, while the Italian equivalent, pancetta, is cured but not smoked. Because of its high-fat makeup, pork belly is ideally suited for low-and-slow cooking methods, which allow the fat to render and baste the meat, resulting in an incredibly tender product.
Where Pork Belly Comes From
The pork belly comes from the underside of the pig, after the loin and spare ribs have been removed by the butcher. It's a large, flat slab that is incredibly versatile. In many cuisines, it is braised or roasted until the skin becomes crispy crackling.
Other High-Fat Contenders
While pork belly is the winner, several other cuts are also celebrated for their high-fat content and flavor-enhancing qualities.
Pork Jowl
Cut from the pig's cheek area, the pork jowl is a fatty cut with high marbling. It is well-known for being cured to produce the Italian delicacy guanciale. The fat from the jowl is known for its incredible succulence and intense, buttery taste. When rendered, it can add significant richness to dishes, especially pasta sauces like carbonara.
Pork Shoulder (Boston Butt)
The pork shoulder, also known as the Boston butt (despite not coming from the rear end) or picnic shoulder, is another significantly fatty cut. It comes from the upper part of the pig's foreleg and shoulder blade area. The high intramuscular fat marbling and connective tissue in the shoulder make it a prime choice for slow cooking and shredding, as seen in classic pulled pork recipes. This fat melts into the meat, ensuring it remains incredibly moist and tender through long cooking times.
Fat Sources for Rendering
Butchers often separate out pure fat for rendering into lard. The quality of the rendered lard depends heavily on the source fat:
- Leaf Lard: This is the pristine, creamy fat from around the pig's kidneys. When rendered, it produces a pure white, odorless lard that is highly prized for its use in delicate pastries, like pie crusts.
- Fatback: This is the layer of subcutaneous fat found along the back of the pig, directly beneath the skin. Fatback renders into a lard with a more pronounced pork flavor, making it suitable for savory applications like frying or sautéing vegetables.
Comparison of Fatty Pork Cuts
| Cut | Location | Typical Fat Profile | Best for Cooking/Preparation |
|---|---|---|---|
| Pork Belly | Underside, from the stomach area. | Layers of fat and lean meat; very high fat percentage (up to 60%+ in some cases). | Low-and-slow roasting, braising, curing for bacon or pancetta. |
| Pork Jowl | Cheek of the pig. | Highly marbled, fatty muscle. | Curing for guanciale, rendering for a rich cooking fat. |
| Pork Shoulder | Upper front leg/shoulder (Boston butt) and lower leg (picnic shoulder). | Ample intramuscular fat marbling and a fat cap. | Low-and-slow methods like smoking or braising for pulled pork. |
| Leaf Lard | Kidney region fat. | Pure, creamy fat; renders into a neutral, white lard. | Baking, pastry doughs, frying delicate foods. |
| Fatback | Subcutaneous fat along the back. | Thick, firm layer of fat. | Rendering for savory cooking, frying, and sautéing. |
How Fat Content Impacts Flavor and Cooking
Fat is a major vehicle for flavor in meat. The high-fat content in cuts like pork belly and shoulder is what makes them so desirable for many slow-cooked dishes. When cooked, this fat renders, or melts, into the meat, moisturizing it and carrying flavor throughout the muscle fibers. A higher fat content also means lower moisture content, which can be a good indicator of the cut's overall richness and tenderness potential.
The composition of the fat itself also plays a role. Leaf lard, being the purest fat on the pig, is prized for its neutral flavor, which won't overpower baked goods. In contrast, the fat from the jowl or belly has a more distinct, meaty flavor that enhances savory preparations. Understanding these differences allows a cook to select the perfect cut to achieve their desired culinary outcome.

Conclusion: Choosing the Right Fat Cut for Your Dish
While pork belly holds the title of the fattest cut, the term encompasses a range of options, each with unique characteristics and best uses. Whether you're seeking the melt-in-your-mouth richness of pork belly, the concentrated flavor of pork jowl, or the forgiving marbling of a Boston butt for a barbecue, a deeper understanding of these fatty cuts empowers you to make a more informed and delicious choice. Ultimately, the 'best' fatty cut depends on the recipe and the desired flavor profile. The richness of fat is a key component to pork's incredible flavor, so embracing these cuts can unlock a new level of culinary enjoyment.
Key takeaways: When it comes to pork, fat equals flavor, and knowing your cuts is essential. Pork belly is the fattiest overall, but other cuts like the jowl and shoulder offer excellent marbling and flavor for specific preparations.
- Pork belly: The undisputed king of fat on the pig, ideal for rich, slow-cooked or cured applications.
- Pork jowl: A deeply marbled and succulent cheek cut perfect for rendering flavorful fat or making guanciale.
- Pork shoulder (Boston butt): A working-muscle cut with high fat content, making it perfect for slow-cooking until fall-apart tender.
- Leaf lard: Pure, mild-flavored fat from around the kidneys, specifically for baking.
- Fatback: A subcutaneous fat layer that renders into a more robustly flavored lard for savory cooking.
Frequently Asked Questions (FAQs)
Q: Is pork belly always the fattest part of the pig? A: Yes, pork belly consistently has the highest concentration of fat among all the cuts, with fat layers intertwined with muscle tissue.
Q: What is the difference between leaf lard and fatback? A: Leaf lard is the fat from around the kidneys, yielding a pure, neutral-flavored lard prized for baking. Fatback is from the back of the pig and produces a more flavorful, 'porky' lard, better suited for savory cooking.
Q: Can I substitute pork jowl for pork belly? A: For some recipes, you can, but they have different fat textures and flavors. Jowl is more intensely flavored and denser, while belly has distinct layers of fat and meat. It's best to use them in their traditional applications.
Q: Why is pork shoulder so good for pulled pork? A: Pork shoulder is ideal for pulled pork because its high-fat content and connective tissue break down during long, slow cooking, resulting in incredibly tender, moist, and flavorful meat that easily shreds.
Q: How does fat content affect the taste of pork? A: Fat is a major carrier of flavor, so higher fat content typically translates to a richer, more flavorful, and juicier eating experience.
Q: Is bacon made from the fattest part of the pig? A: Yes, streaky bacon (American style) is typically made from cured pork belly, which is the fattest cut of the pig. Back bacon is from the leaner loin section.
Q: Is it possible for a leaner pig to have less fat in the belly? A: Yes, the fat content can vary significantly based on the animal's breed, diet, and slaughter weight. Leaner pigs will produce leaner belly cuts, although it will still be a fatty cut relative to other parts of that same pig.
