Preheat your oven to 450°F. Arrange the bones on a wire rack set over a half-sheet pan, then drizzle with oil and sprinkle with salt and freshly ground black pepper. Roast in the preheated oven for 45 minutes, or until the bones are richly browned.
Instant Pot
Transfer bones to Instant Pot, add veggies, spices, herbs, water, and vinegar, cover and cook on HIGH PRESSURE for 2 hours, with a 10 minute natural release, followed by a quick release of remaining pressure and uncover.
Strain
Strain and reserve clear broth, discarding solids. Mix in turmeric, lemon juice, ground black pepper, and salt. Let cool, then refrigerate covered.
The next day, the fat will harden and solidify at the top; spoon it out and discard. Store the broth in the fridge for 3-5 days or transfer to freezer-safe containers, leaving space for expansion, and freeze for up to 3 months.
Serve
Add desired amount to a small saucepan and heat over low heat until hot. Enjoy in a cup.
If frozen, thaw in the refrigerator before reheating.
