Adding pork heart to bone broth provides several benefits:
Flavor: Pork heart imparts a rich, savory, and slightly sweet flavor to the broth.
Nutrients: Pork heart is a good source of protein, iron, zinc, and vitamins B6 and B12. These nutrients contribute to the nutritional value of the bone broth.
Collagen: Pork heart is a particularly high source of collagen, which breaks down into gelatin during the simmering process. This adds body and thickness to the broth, making it more viscous and flavorful.
Minerals: Pork heart also contains minerals such as calcium, magnesium, and phosphorus, which can be leached into the broth and contribute to its overall mineral content.
