I recently came upon a few pounds of grass-fed beef bones.
My friend told me that if I crockpot them on high for like 3 days, the bones will become soft and edible. Have any of you tried this? Could you give me the details of your experience? How long will I need to do it? Can I use tallow as a base? Should I use some water? Vinegar? I would like to hear from someone else's experience before trying it myself.
I haven't been able to find much by searching but I might just not be looking for the right keywords. I don't just want to make broth, I want to eat the bones.
If you're going for serious bone broth, add a little vinegar, a lot of water, and let them simmer 24 to 72 hours. Don't add vegetables early in the process; they tend to get bitter. You won't really need a base (you mentioned tallow) it will take care of itself.
Since the bones are what you're after, cooking this too long isn't much of a concern, other than you don't want it to dry out and burn, off course. Check as you go to see when they get soft enough.
I crock pot them on low for about a day. I only use water, a little wine and salt. I don't like how it tastes with vinegar or cooked all to hell. My meat market sells soup bones that have some meat on them, lots of cartilage and connective tissue, and a ball joint that has been cut in quarters. I also throw in a pig's foot. I pour the broth into glass jars and in the fridge the fat goes to the top. I can save that for cooking. The broth turns into beef jello. So good! I save all the meat and make burrito bowls or whatever.
Its funny that this question came up as I just cooked up some marrow bones in a crock pot.
They were selling grass-fed beef bones for 2.99/lb at Whole Foods so I picked up a couple lbs.
If you JUST want to eat the marrow, I suggest simply roasting them in the oven (450 for ~15-20 minutes).
You could then spoon it out and eat it straight up, or, spread it on something. I made some coconut flour and organic red palm oil bread, toasted it, and spread it with marrow and a parsley/radish/lemon juice/EVOO salad. It was a party in my mouth.
If you're set on using a crock pot, however, I would suggest taking the bones...
And some beef (I used a grass-fed 3lb beef chuck shoulder roast that was on sale at Whole Foods for $3.99/lb woot woot!)...
Smear the roast with bacon fat and sear it on all sides...
Then, toss the roast, the bones, 10 cloves of garlic, 2 cups of previously made meat jello (ie. cold bone broth), dried herbs (rosemary, parsley, and thyme), and a water into your crock pot...
Set it on "low" and forget about it for awhile (I let mine go about 16 hours total). By then the roast will be falling apart and the marrow and connective tissue will have melted into the broth which you can sop up with the shredded meat.
I have a Kenwood slow cooker. I don't know how to do it but I know HOW NOT TO DO IT.
There are two settings - high and low. Use high, don't use low (I used low and it was a mistake). I let it simmer for 24 hours - don't do it, I overcooked it. I'd say 8 hours would be enough.
I made broth jello over the weekend. I filled the crock pot with beef knuckle bones and feet, then covered with water and cooked on low for 36 hours. I let it cool enough to handle, removed the scum off the top, pulled out the bones, strained through a colander, then strained again through a fine mesh sieve. I put it in the fridge and once the fat hardened, removed it. It gave me 8 cups of beautiful jello.
I was too lazy this time to roast the bones, but when I do it, I put them in the oven for about an hour, or until the house smells like roast beast, then throw everything in the crock pot in the manner above. I discovered I like the flavor better without any veggies or vinegar in the mix. I've never tried it with wine; I'll bet a nice red would taste good.
