Step 1

Dump everything into a large stockpot, and bring to the boil.

Step 2

Once it's boiling, reduce the heat to low, give the pot a stir, cover with a lid, and allow to simmer for 1-2 hours, depending on how strong you want your broth to be.

Step 3

Once the broth is done, carefully strain it into a suitable lidded container. Set aside to cool, then keep in the fridge for a week or so, or in the freezer for up to three months. (note 2)
