How To Blanch Bones?
It is very easy to blanch bones. All you have to do is cover them with cold water, then let them boil, and then after that start cooking them for twenty minutes (aggressive simmer). After this drain them and roast it to caramelize and brown them so that they may taste better.
The bones that you are using are probably going to have some bits of meat on them, and impurities from the bones are going to come out. All of these unpleasant bits that are not going to harm you, but in order to get that nice, clean, rich stock out of your bones, you will have to parboil your beef bones. Blanching your bones for 15-20 minutes helps to remove all of those ugly bits that, well, makes your bone broth look and taste a little gross. I suggest, particularly if you are making beef bones broth, you really blanch them first.

If you are going to be making bone broth on a regular basis, you might as well adjust the purchase of meats to account for your bone broth needs. While you could limit your recipes to bones and water (with some vinegar added in for good measure), you could also include herbs and vegetables to boost the nutritional profile of the broth. In addition to using bones, water, vinegar, and aromatics to make a broth by yourself, you can also add herbs and vegetables to boost its nutritional value. Spices may be added at the time of the initial cooking, or you can prepare a base, and then simmer part of it with additional spices later, for around 1 hour.
| To Blanch bone | Shelf life |
| Cover the bone with cold water | Raw bones in refrigerator 3-4 days |
| Bring to a boil | Bones broth Up to 7 days in refrigerator |
| Let them cook at an aggressive simmer for 20 minutes before draining and roasting | Cooked bone 3-4 days |
Bone broth needs to be simmered for as long as you can stomach–at least four hours–to ensure all of the collagen and gelatin has broken down and infused into the broth, but preferably anywhere between 10 to 12 hours or longer. Make sure that your stock pot is big enough, add enough water to cover the bones, bring to the boil, reduce the heat to low, and cover. For this step, cover the bones with cold water, bring to a boil, and allow the bones to simmer vigorously at a low simmer for 20 minutes, and then strain.
With the other method to get clear, you will heat water to a simmer, and then blanche bones and meat for 10-15 seconds. Blanch bones in cold water for 20 minutes, before taking it to the boiling point, then simmer for an additional 20 minutes at a low simmer, then grill. Once you have blanched them for 20 minutes or so, roast the bones in the oven along with a few carrots on very high heat. If you want, you can also blanche the bones to remove the impurities that might ruin the flavor, soaking in boiling water for 10-15 minutes, and then roasting.

Using boiling water to cleanse your bones eliminates any impurities and helps create a clean, crisp stock. Then, the blanched bones and aromatics are added to fresh, cold water, and then boiled down to create the final broth. Blanching strips the bones of their impurities and helps to produce a cleaner, clearer broth that is what you are likely after. The bones should be blanched to remove any bones you do not want in order to make nice, clean broth.
Not all bones are created equal, so try using 2-3 different types of bones for making broth. You can usually get bones at any butcher, but be sure that it is from an animal that was treated and fed appropriately.
When you have finished the bones, remember to deglaze your roasting pan with some water, and use this liquid in the base of the stock. Transfer your bones and vegetables back into at least two 8-quart stockpots, scraping up whatever bits and juices are left in the roasting pan with a metal spatula and some water, if necessary. Wash out the stockpots used for the bone-in blanching process (this is super important) and split the roasted bones and vegetables into the two pots.
Drain water off of a larger pot, transfer venison leg bones to baking tray to roast next step, then rinse out pots. After bones are immersed, thoroughly rinse bones and put in large pot filled with water. The bones are then placed in the large pot filled with cold water until the water covers the bones completely. I simmer them for one hour, skimming off any foam at the top, and then I pull out the entire chicken and strip the meat from the bones. Then I rinse the bones with cold water, then I put them back into the simmering pot for one more hour.
If you are using bones left over from baking the chicken full, or making roasts, you can skip roasting as technically, the bones were already roasted in the original baking process, but for any bones that are uncooked or blanched, I strongly suggest going in the oven to impart better flavour. I like following the longer roasting process for bones first before baking, which does add some extra gear. If using chicken bones or chicken feet, blanching is not as critical, but beef bones do indeed require blanching, particularly if you want clearer stock.
With beef bones, though, I always blanch the bones prior to roasting–it really does make for a more flavorful broth. Note: You can blanch raw bones prior to roasting, optionally, by soaking in boiling water for 10-15 minutes. For caramelization, roast bone in the liquid for one to two hours, depending on bone size and length.
Stock is typically a lighter-bodied liquid made by cooking the meat, sometimes the bones, in water with aromatics for an hour or two. Bone broth is a flavorful, nutritious, collagen-rich liquid made by simmering meat bones rich in marrow (beef, chicken, turkey, pork) in water for a long time. Bone broth is the stock made from boiling animal bones and water (with a dash of apple cider vinegar) over a longer period of time.
Roasting bones for broth helps to extract the flavors and trap all of the depths that ultimately infuse your soups and stews with a richness. If you would like to see your broth congeal when chilled, throw some bones, joints, knuckles, even feet into your pot before you cook. Once the broth is cooked (see notes below), use a slotted spoon or spider to remove any larger pieces of bones and vegetables, if using.
How do you prepare bones for the stock?
You can cook beef, hog, or chicken bones for 24 or 48 hours to prepare the bone broth. Make sure the bones are completely submerged in water before placing them in a saucepan on the stove or a crock pot. Keep an eye on your pot while they cook as you might need to add water.
Why do you parboil bones?
The method of parboiling the bones cleans the bones, gets rid of the filth and debris inside of them, and gets rid of the stench of stinky iron. It also signifies the distinction between a nasty, foggy broth and a tasty, clear broth.
How long do you parboil bones for?
Marrow and knuckle bones, which contain a lot of collagen, can be pre-boiled to eliminate funky flavors. The bones should be placed in a kettle, covered with cold water, and brought to a boil for 20 minutes. Drain, then save the boiled bones while throwing away the water.
