Simmer the chicken with the spices
40 minPut the chicken in a large pot, add 2 liters cold water, and heat. As it comes to a boil, skim off the foam with a spoon; this is key to a clear broth. Add the halved onion, bay leaves, cinnamon stick, one 4 ml measure allspice, and 8 g salt. Reduce the heat and simmer for 30 minutes with the lid slightly ajar. Insert a thermometer into the thickest part of the meat without touching the bone; it should read 74°C / 165°F. Touching bone can give a misleading reading. Remove the chicken, strain the broth through a fine-mesh strainer, and measure out 1.2 liters.
