As to masking flavors: I recall reading that we taste things differently depending on number and density of taste buds. Some people are super tasters, as indeed most children are, and can be put off be strong flavors such as broccoli or kidneys and liver. If the " masking" is good primal food, I don't see that as an issue. Plus, we change with time and experimentation. I hated asparagus when I was a child and teen, not till I went to college did I learn that asparagus could be delicious when not over-cooked. If a few tweeks get people to try more good primal foods they will benefit and in time get more adventurous with offal-- and lots of foods thet may have thought awful.
This time, like all times, is a very good one, if we but know what to do with it. Ralph Waldo Emerson
