Beef, retail cuts, separable fat, cooked

This refers to the fat trimmed off a beef roast or steak after cooking, the firm white layer separated from the muscle meat. Rather than being eaten as a cut on its own, it's typically rendered down into tallow, a cooking fat used for frying, roasting potatoes, or adding richness to a pan sauce or gravy. Some cooks crisp small trimmings in the oven as a garnish, similar to pork cracklings, adding a savory crunch to a dish. In traditional cooking, saving and rendering this trim rather than discarding it is a common way to stretch a cut of beef further.

To store it, trim the fat before or after cooking, render it slowly in a pot over low heat until it liquefies, then strain and keep it in a sealed container in the refrigerator or freezer, where rendered tallow keeps for months. The numbers make its role clear: 680 calories and 70.3 grams of fat per 100 grams put it firmly in cooking-fat territory rather than protein-source territory, despite showing 21% Daily Value for protein from the small amount of attached meat. Used a spoonful at a time, it adds flavor to root vegetables, potatoes, or a skillet of greens without needing much beyond what's already in the pan.
