For me, I mix duck, chicken and deer bones, add a cinnamon stick, 3-5 whole star anise, 4 inches of sliced ginger,, 10-20 cloves of garlic, green onions, and 1/2 cup of leftover lacto ferment liquid (from mustard greens ideally). I blanch or roast bones, put everything in a pressure cooker for 2 hours, release pressure and remove all spices and veg matter you can, then run for another 2 hours. Strong, tasty broth, good for drinking or cooking with.
