- Simply cover the carcass and/or veg bag with cold water and add the remaining ingredients.
- Bring to a boil and skim off the scum that forms at the surface. Then, turn down the heat and let it gently simmer for 3-4 hours, skimming when necessary.
- Strain the broth and discard the solids. Use immediately or store in a airtight container in the fridge for 4 days or in the freezer for a few months.
Alternatively, this can all be chucked into a crock-pot and left to cook on low heat for 8-12 hours.
