For the most simple way I've found to make bone broth, you'll need:
2-3 lbs of good quality bones (grass-fed, or pastured)
1-2 TBLS Apple Cider Vinegar (Bragg makes a great raw one)
Sea Salt (I love Real Salt) (I start with about a TBLS but individual preferences will vary)
Put the above ingredients into a good-sized crockpot, and cover with filtered water. Depending on the types of bones, you'll want to cook it for 12-24 hours. As you know by now, I'm not much of a cook (but luckily my husband is!), so I keep this super simple so that I am more likely to make it. I'll make a big batch per the instructions above, remove the bones and take out the marrow for a yummy healthy treat, put the broth into glass containers with lids (we use pyrex glassware or quart-size canning jars, save a little room on the top for expansion, and freeze them. Then I take the bones that I've just removed the marrow from, put them back in the crockpot and start the process over again. You'll find that the first batch is a bit more gelatinous when it cools. The more gelatinous, the better. You can even add extra collagen if you have it in powdered form - I use Bulletproof Upgraded Collagen.
In this pic you can see that the broth on the left is much more white. We eat LCHF (Low Carb High Fat), and we use high quality grass-fed bones, so the fat content is rich in Omega 3s and my husband Tuan doesn't like to waste it. So he makes what he calls "bone broth latte" out of it. He leaves the fat in the broth, then puts it in the blender and it comes out looking like the broth in the jar on the left.
The small glassware at the front has all of the delicious marrow separated. This is a true superfood, so we eat that right away as a special treat.
As for the remaining bones on the right of the photo, these are super soft now. In fact, most of these will crumble in your fingers and basically turn to sand. We don't want these to go to waste, and they are so soft that we consider these safe for our dogs and farm animals to eat, but you would need to evaluate your bones individually for safety before doing this.
We've always got bone broth available at home. We'll have it for breakfast some days, use it as a meal on a day that we are fasting, add it to other recipes in place of water or broth, or even put it in the baby bottle in place of milk or water (over 6 months of age). As long as there is enough salt in it to be palatable, I'll typically heat it up on the stove and drink it plain. But I encourage you to be more daring and start adding it to your other recipes or dress it up as its own more exciting meal!
