FAQ
What does 'separable lean and fat' mean?
It means the nutritional values account for both the lean meat and the attached fat that you would typically eat, trimmed to a standard 1/8 inch.
Why is the carb count 0g?
Pure, unseasoned meat contains no carbohydrates. Any carbs in a prepared dish would come from sauces, marinades, or side dishes.
Is this the same as a ribeye steak?
Yes, the ribeye steak is cut from the same rib section (ribs 6-12). 'Prime Rib' often refers to the whole roasted section, while 'ribeye' is a steak cut from it.
