Stoney,Hi. Most " sportsmen " are not able to figure out the offals.....but it is so nice when one helps with a drag and they give them all to you or tell you how far back they left them. Amazon used to have used copies of a fabulous cookbook titled " The LL Bean Game and Fish cookbook ". The recipe for Venison stew is extraordinary, and you should absolutely save the kidneys and use them here. The corned caribou/venison in prep for a New England Boiled dinner is unbelievable. The neck sectioned and included in the same brine can be wonderful for those pickers in the family ...the sandwiches are fine, fine. I braise the heart whole in a very spicy courte bullion and later 1/2 " slices with mayo for a very delicious and quiet sandwich on stand later. The Icelandic Gravlax, ( I soak for 48-72 hours ) and poached salmon are to die for. Very too bad about the liver !! venison is the finest liver to me. You could have frozen it and made the best pate' " EVER. 3/4" venison liver steaks salted and peppered in 1/2 olive oil and butter and pink inside with a golden crust ? well, with a hearty Rhone.....HEAVEN, and no need for onions etc.
I really gotta go to my freezer now. Good luck, and have an offal time ! Dave
