* I slightly overpaid (🤣) for the bones from my regular local grocery store ($2.50-$3/lb). They don't reliably have them in stock so I just buy them and freeze them when I can find them (they're with the other cellophaned meats).

* Roast them for 20min per side @ 450°F.

* Start heating up water + 2Tbs white vinegar in the instant pot.

* Chop in some carrot and celery (no other seasonings tho 'cause doggos).

* Drop in the bones and make sure they're totally submerged.

* Pressure cook for 2-2.5hrs.

* Natural release w/out heat (~40min?) until the pressure bottoms out.

* Strain the bones, veggies, detritus. I keep any meaty bits; they're mostly tasteless but I save them to mix into omelettes.

* Pour into mason jars.

* Run cool water around them.

* Loosely cover with cap, put in fridge.

* Later: skim off the congealed fat.

* Freeze most of the jars.

Serving:

* Put a spoonful in a small bowl w/a tiny bit of water.

* Microwave for 15s.

* Pour over dog food.
