Thanks for the response.

The red stuff is muscle tissue, called "meat" or "lean".

You answered the big question I had. Lean is an adjective, not a noun, but they use it as a noun.

Now, how much filler is in hamburger meat ?

Since the 'butcher' is 'estimating' the amount of fat vs. muscle tissue in the meat going into a grinder, then these 70/30 or 80/20 or 85/15 labels are not exactly accurate, are they ?

Jack Sprat could eat no fat; his wife could eat no lean.

Now there is a good question. One would hope little to none. However, you can stretch your ground beef dollars by adding in TVP. Textured Vegetable Protein. Look it up. Fairly cheap and easy to use. It really stretches the meat you use for meat loaf and such. It's a good thing to have stashed with your Preps.

But I will never use it again in grilled burgers. There are just some places you don't scrimp. And my custom burgers are at the top of that list.

Supposed to be zero, if you're buying fresh hamburger meat at the grocery.

then these 70/30 or 80/20 or 85/15 labels are not exactly accurate, are they ?

I don't know how big the error bars are. Every measurement has error bars. The products are visibly different, though.

Actually, it's a verb, noun, and adjective. I lean over to touch my toes. That building has a lean. That's some lean beef. Lean is also further defined as a noun in that it is "the part of the flesh that consists of muscle rather than fat"
