I gave them a good spray and then returned them to the soaking pot.
Finally the hooves were ready for stock! I used the large slow cooker and 2 of the hooves with the usual vinegar, veg and seasonings and let it simmer away for 48 hours. The results were impressive! The broth came out a lovely deep colour and had a nice thickness to it. And interestingly enough, I've been eating some soup I made with it each day, and I'm the only one in my family of 8 who hasn't been hit hard with the flu!
So Pollyanna must have been onto something taking a sick woman some calf's foot jelly!
