I love heart of any animal. For big game hearts I trim all the white stiff off and soak in salt water for a night. Then I put some liquid in a pot, could use wine, beer apple cider, bullion etc. and roast on 375...don't overcook it you want it medium rare, tender. They ways I liketo eat it are sliced when out of the oven with mashed potatoes and gravy and some other veggies and a glass of red wine. Put gravy on the heart too, it'll be like roast beef. Then next way and maybe my favorite is the leftover, after cooled is to make heart sandwhiches. Slice heart thin and layer nicely on an oinio bun or beer bread, cheese, lettuce tomato, mayo, mustard or my favorite, raspberry honey mustard...just right for after a long moring hunt
