STEP 1/20
Soak the bones in water to drain the blood
I drained blood for more than half a day
STEP 2/20
Pour water into a bony bucket and fill with bones
STEP 3/20
When it starts to boil, boil it for another 20 minutes and turn off the heat
STEP 4/20
When you boil it for the first time, a lot of impurities come up
I throw away all the water that was first boiled
STEP 5/20
Wash the bones thoroughly in water
STEP 6/20
Wash the large container, add the bones again, and fill with water
STEP 7/20
Please open the lid and boil it
You can make it for 4 to 6 hours, but I made it for 6 hours
STEP 8/20
Turn off the lights in six hours
STEP 9/20
Please put the first one in a different container
STEP 10/20
It's the 2nd round
Fill the water again and bring to a boil
I'll boil it for 6 hours
STEP 11/20
Cool down the first one and remove all the oil
STEP 12/20
The first batch of skimmed oil was put in a different container
STEP 13/20
The 2nd round was good, too
Transfer to 2nd batch and remove oil when cold
STEP 14/20
Add water and bring to a boil it
STEP 15/20
After the third round, please remove the second round of oil
STEP 16/20
Wait until it cools down for the third time and remove the oil
STEP 17/20
You can throw away the bones as general waste
STEP 18/20
Mix the first, second, and third steps and boil them again
Let it boil for about 30 to 40 minutes
STEP 19/20
You can put the boiled beef bone in a zipper bag and keep it frozen
STEP 20/20
I took out a pack of frozen beef and boiled it, seasoned it with salt and pepper
Cut the green onions and enjoy it
When you clean up the sink and pot, you need to wash it with hot water to wipe off the oil
If you wash it with cold water, the oil hardens and it's hard to wipe it off
