Beef stock

At 6500 feet, 13 1/2 lbs. of pressure = 240+ degrees

With the high-pressure canner I bought this summer and 30 lbs. of beef bones from El Morro Valley Ranch in the freezer, I had to make my own version of all natural organic beef stock this past weekend. I started with a bike ride to the coop for organic celery and carrots. They had both.  The next stop with the BOB trailer was The Water Store for 4 gallons of purified water, and then back home, slowly. 

5 pounds of thawed beef bones

I browned batches of the bones in olive oil, and then, with about 15 lbs of the bones and gravy, I filled the stainless steel brewing kettle with nearly all the water. After bringing it all to rolling boil, I skimmed foam from the top for about 10 minutes.  I simmered the bones alone for about 3 hours before adding a pound each of the celery, carrots, and onions, a handful of bay leaves, whole peppercorns, sea salt. Then everything simmered overnight. In the morning I carefully skimmed and set aside about an inch of fat from the surface of the broth, and used a slotted ladle to remove all the solids. After heating the cans and lids to 180, I filled 6 quarts with the rich smelling broth. Using a fine steel mesh sifter I was able to filter out all of the particles of meat and vegetables, and was left with a uniform dark tan broth. 

Removing the jars after waiting the hour or more it takes the canner to depressurize

The Ball Blue Book calls for 20 minutes at 10 lbs. pressure for stocks (a considerable difference from any meat stew recipe which is processed for 120 minutes or more). In Gallup at 6500', to achieve the safe temperature of 240 inside the jars, I try to keep at 13.5 lbs of pressure. The pressure weight on the Presto canner I bought is set for 15 lbs, so I adjust the big burner on the stove to around med-low to low to keep that pressure, and adjust frequently to keep it above the minimum of 13 lbs. and the over processing (higher temperature) of 14 lbs. and above.
