Since my DH used to be a hunter, he would always bring home the heart and liver. I had no idea how to do them but his mom told me to make pickled heart. I soaked it in salt water over night and then rinsed and cut in half. Put in a pan and covered with water, salt and pepper and boiled for about an hour. When it was done, I cut it up into bite size pieces and put it in a mixture of vinegar, water and s & p and let it sit in this mixture for about 2 weeks in frig. Then it was ready to eat. I could never bring myself to eat it but DH and kids loved it!
