Richard Perkins and Louisa demonstrate rendering tallow and making bone broth from large animals. Bone broth simmers 24 to 50+ hours in cold water with vinegar to draw minerals; tallow gets chopped, rendered wet or dry, then double-clarified with salt and water to remove odor. Pressure canning at 120°C or boiling 120 minutes at 100°C kills spores, and one cow yields broth for months.

Questions this video answers

At least 24 hours (rule-of-thumb; 24–48 hours recommended).

Examples given: 30 hours, ~28–50+ hours (one pot described as cooked at least ~50 hours after combining batches).

About 150 milliliters per large pot (Louisa: "Maybe like 150 milliliter").

If no pressure canner, Louisa suggests at least 120 minutes at 100°C (though she notes pressure canning is preferred).

Transcript states spores die over ~116°C; Louisa references safety at 120°C under pressure.
