Directions
1. Remove any excess fat from the chicken carcass and wash off under cold water.
2. Place all the bones into a pot that will hold all the ingredients, leaving 5cm at the top to skim.
3. Add the other ingredients and cold water, and bring to a simmer; immediately skim all the fat that rises to the surface.
4. Turn the heat off and allow the bones and vegetables to sink. Once this has happened, turn the heat back on, skim and bring to just under a simmer, making as little movement as possible to create more of an infusion than a stock. Skim continuously.
5. Leave to simmer for 12 hours, then pass through a strainer into a clean pan. Reduce down rapidly until you have 3 litres remaining.
