A simple broth that can be made ahead and used as needed.
Place all ingredients in a stock pot and pour in enough water to cover.
Season with salt and pepper and bring the pot up to a full boil.
After 90 minutes, strain the broth and discard the solids.
Let the broth cool and then pour into a re-sealable container and keep in the fridge for 1 week, or place in the freezer and store for up to 3 months.
