Making stock is easy because the ingredients are percentages (by weight) of a whole. The breakdown is 100% water, 50% bones, 10% mirepoix. One gallon of water weighs eight pounds, so for one gallon of stock you use one gallon water, four pounds bones, and 12 oz of mirepoix (onions, carrot and celery chopped).
Other ingredients are:
Sachet (parsley stems, bay leaf, sprig of thyme, peppercorns)
Tomato paste
Red wine
You will also need a large stockpot and a roasting pan.
Here's the beef bones, just over 4 lbs.
And the sachet.
Wrapped in cheesecloth, with a string or something tied on the end so you can connect it to the handle of the stockpot for easy removal.
I roughly chopped the mirepoix. Also, for stock, you want your mirepoix to be 50% onion, 25% carrot and 25% celery.
Roast the beef bones at 400 degrees . . .
until they are well browned.
Then, slather on the tomato paste with a spatula.
And throw them back in the oven . . .
for just a short time and the paste is melted into the bones.
Remove the bones from the pan and put them in the stockpot, and drain the fat off, discard.
Then take the red wine and deglaze the pan to get all the bits of meat and fat off the pan and pour it into the stockpot with the bones.
Then put the mirepoix in the roasting pan and throw it in the oven.
While the mirepoix is roasting, add the water (cold) to the stockpot. You want cold water because then more of the impurities in the bones are removed if the water goes through the full range of temperatures. Some impurities are removed with cold water only.
Add the mirepoix and sachet; bring up to a boil
Skim the impurities off the top right when it gets to boiling point, and turn the heat down to a simmer.
A beef stock is usually ready in 6-8 hours of simmering.
I left mine on overnight (about 10 hours).
Remove the sachet.
Line a strainer with cheesecloth . . .
Remove the bones with tongs . . .
And pour the liquid through the strainer.
At this point, you want to cool it down quickly so harmful bacteria have a lesser chance to grow, so you want to vent it in an ice water bath.
The sanitation rules say that the product must be down to 70 degrees within two hours, and down to 40 within four hours after taking off the heat.
Here are the bones after simmering all night.
Also, you don't want to put a hot product in your refrigerator because it will heat everything else in there up. I made sure i got it down to about 60 before i put it in the refrigerator.
Next time, i'll use the stock in a sauce
