As far as organ meat goes, heart is probably some of the most tame you can try. When I first had this, I honestly thought it was an elk roast, or perhaps moose. It was that good! Bear in mind that it is a very low-fat cut, so over cooking will dry it out quickly. This is one I have made a few times for a Sunday roast. When I didn't tell people what it was, they assumed it was just a beef or venison roast!
