I'm trying a beef bone broth recipe that is short on details... it basically says to cover the bones with water and simmer for 48 hours in a slow cooker.
Based on Google, other recipes don't say to cook for anywhere near that amount of time, but I decided to try it anyway.
I started with 2½ pounds of bones and about 3 quarts of water in a slow cooker. During the 48 hours the liquid reduced enough that it was no longer covering the bones, so I added more boiling water and continued cooking. I had to do this a total of 2 times and the final result was about 1¼ quarts of broth (after skimming the upper layer of fat).
My question is: given the initial 2½ pounds of bones, how much broth should I end up with? Is 1¼ quarts of broth going to be super-concentrated and in need of dilution, and if so, how much water should I add?
