Care to describe what is not beef in the raw 85 or 90% hamburger bought from the local Safeway Store. Are they using pork fat or what?
I could be wrong but I thought that figure had to do with fat percentage of the ground product. As in 85% or 90% percent ground trim mixed with 15% or 20% ground fat.
I have always presumed that to be beef fat when describing ground beef, pork fat when ground pork, etc.
No idea. No Safeway anywhere near here, so I never bothered to look. Probably some sort of preservatives.
If ground beef is labelled 85/15, etc., then that means it’s 80% lean beef and 20% fat. It’s just a measure of how lean the ground beef is.
80/20 is generally considered to be the best ratio for grilling burgers, as it won’t shrink away to nothing, but still has enough fat to keep it nice and juicy. :)
