Liver vs Testicles — What's the Difference?
Quick Answer
Liver (beef liver) and Testicles (testicles (criadillas/Rocky Mountain Oysters)) are not the same cut: Liver is offal primal (Abdominal cavity — behind the diaphragm, forward of the kidneys); Testicles is offal primal (Removed at castration — sold as a standalone cut).
Side-by-side
| liver | testicles | |
|---|---|---|
| Primal | offal | offal |
| Muscle / location | Abdominal cavity — behind the diaphragm, forward of the kidneys | Removed at castration — sold as a standalone cut |
| Character | The largest internal organ; iron-rich, with a strong mineral flavour that mellows when soaked in milk or acidulated water. Seared quickly to avoid overcooking (which makes it grainy and bitter). Widely eaten grilled, fried, or blended into pâté. Standard offal market cut across all beef-eating regions. | Bull testicles. Sold and prepared as a standalone cut across multiple cultures. Known as criadillas in Spain and Latin America, Rocky Mountain Oysters in the US west, and Prairie Oysters in Canada. Typically peeled, sliced, and deep-fried or grilled. |
Key differences
- Texture and slicing: compare fibrous, grain-heavy cuts vs more tender steak-style muscles based on each cut’s description.
- Retail naming diverges by country—always map through a canonical cut when translating menus or labels.
