Most of the raw foods I've tried are quite tasty, once I open my mind to them. I tried lamb kidneys first because I could get them first. Not bad. Then, lamb's liver. Very tasty, a favorite. Then, lamb's heart. I could do without it. I can get beef marrow bones. A delicacy.
The orange-juice/liver blend doesn't appeal to me at all. I wonder if the blend was therapeutic, or just a way of getting liver down the hatch? My own belief is, if you hate the taste, that food is not right for you. When/If the taste changes, then eat it.
