Long before bone broth was trendy, it was just dinner. Every culture has a version of it because every culture eventually figured out that the most nourishing parts of an animal aren’t the ones you usually think of.
Add everything to a large pot or slow cooker. Cover with cold water and let it sit for 30 minutes, the vinegar helps draw minerals out of the bones. Bring to a gentle simmer and let it go low and slow: 12-24 hours for chicken, 24-48 hours for beef. Strain, cool, and store.
A good broth should jiggle like jello when it’s cold. That’s the gelatin you came for.
Sip a warm mug in the morning. Cook your rice and grains in it. Use it as the base for any soup, stew, or pan sauce. A jar in the fridge means a nourishing meal is always twenty minutes away.
