Add all ingredients into a large pot.

Bring to a boil over medium-high heat.

Once boiled, reduce heat to medium-low and simmer for 10-12 hours (covered).

Check occasionally and add more water if needed.

After 10-12 hours, the broth should be milky and slightly creamy. The longer it boils, the creamier it becomes.

Add salt to taste.

Let cool before transferring to a container and chilling in the fridge for at least 4-5 hours to set the gelatinized broth (or freeze).

A day before using, transfer to the chiller. Alternatively, use straight from the freezer.
