My friend Patricia recently showed me how to make bone broth. Mike found a bag of bones in the dog food section of the supermarket. After 24 hours of simmering we got a thick, rich, gluggy pot of broth. We are having it for lunch each day as soup. It has added kumara, carrot, parsnip, celery, kale, onion and leek, most of which is from the garden. Matthew has coined it ‘Dog Bone Soup’.
