Definition
Meaning
The high-quality fat found around the kidneys of a pig, valued for making lard and pastry.
In butchery and cooking, this refers specifically to the dense, flaky internal fat surrounding the kidneys, prized for its purity and high smoking point.
Linguistics
Semantic Notes
A compound noun where 'leaf' refers to its layered, flaky structure (like leaves of a book), not its origin from a plant. The term is highly specific and not used for fat from other animals or other parts of the pig.

- Avoid direct translation ('лиственный жир'), which is nonsensical. The correct equivalent is 'почечный жир' (kidney fat) or 'сальник' (omentum fat), though not a perfect match.
Common Mistakes
- Referring to any pork fat as 'leaf fat'.
- Using 'leaf fat' for beef or lamb (specific to pigs).
- Confusing it with suet (which is the equivalent hard fat from cows or sheep).

What is 'leaf fat'?
FAQ
Frequently Asked Questions
No. Leaf fat is the raw fat. Lard is the product after the leaf fat (or other pork fat) is rendered (melted and purified).
For the specific textural qualities in pastries, it is difficult to substitute perfectly. Rendered leaf fat (leaf lard) is considered the gold standard for flakiness and neutral flavour.
It refers to the physical structure. The fat is found in a mass that separates easily into thin, layered sheets or 'leaves', unlike the harder, more solid fat found elsewhere on the animal.
It is a specialist ingredient. You would need to request it specifically from a butcher, a farmer's market vendor selling whole pigs, or a specialty online meat supplier.
