I've eaten fresh, warm liver from a freshly killed cow, and it tasted - less bad. But it still tastes like metal. Maybe different people taste different parts of the flavor profile more than others. Oddly, it's fine raw. Honestly kind of creamy, but hard to eat in large quantities for me, personally. That pound of mashed nearly-raw liver was still so bloody it was crusting on my lips. Just not a pleasant experience.
