How to blanch bones?

The bones are blanched by boiling bones in water after covering the container with a lid. When the water starts boiling, the impurities float on the surface and are then skimmed from the surface. The murky water is then drained. The main reason behind the blanching of the bones is to prepare a clear extract of the bones.

Recipe for making bone broth:

The recipe for the preparation of bone broth includes the following steps:

  • Take bones and carcass of 1 chicken, 12 cups of filtered water, 2 tbsp of apple cider vinegar, 1 pinch of salt, 1 pinch of black pepper, rosemary, and 1 sliced lemon.
  • Take a large pot or Dutch oven and add bones in the pot.
  • Fill the pot with the filtered water to the level so that all the bones are submerged in the water. For this purpose, almost 12 cups of water are sufficient.
  • Add some salt and pepper to the broth to season it.
  • Now, add apple cider vinegar to the broth. The acidity of the vinegar breaks the collagen and makes it abundant in the broth. You can also replace the apple cider vinegar with lemon juice.
  • Put the pot on the stovetop and bring everything to boil.
  • Once the water starts boiling, slow down the heat and let the solution simmer for almost 10 to 12 hours. the broth should be reduced by 1/3 to 1/2.
  • Strain the broth and discard the bones.
  • Pour the broth into the jars and store the broth in the freezer for about 1 to 2 months. The space of a couple of inches should be left on the top of the jar to let the broth expand upon freezing.

Tips for making the perfect broth:

Some of the tips for the preparation of bone broth are as follows:

  • The bones should be properly blanched and the foam which appears on the surface of the broth should be removed. This white or grayish foam on the surface may be the reason for the off-flavors in the broth.
  • The blanching should be done by simply cooking the bones over low heat for about 20 minutes and the foam is then skimmed off from the surface.
  • To get the rich and meaty flavors in the broth, the meat should be roasted.
  • The bones should be browned and then deglazed with water or other liquids to get the perfect brownish color in the broth.
  • Simmer the broth for a long time to extract the bones to the maximum extent. For this, you should simmer the bones for about 10 to 12 hours.
  • The broth should be cooled quickly as the slow cooling can allow the bacteria to grow in the broth.
  • For quick cooling, you should immediately pour the broth into another pan and continuously stir the broth until the temperature of the broth becomes equal to that of the room temperature.

Ways to make broth at home:
