Liver and onions.
now, kiddies, let me tell you about liver. You either like it or you cannot abide the taste of it. Why? Because there's actually a receptor on your tongue that if it's active (via genes ala dominant or recessive) you taste a certain enzyme in the liver that makes it completely unpalatable to you...bitter, nastiness. I am the only person in my immediate family that possesses this genetic trait...and my mother was of the opinion that you eat what I cook. I got sick on liver nights. After awhile mom stopped making me eat it.
Even the smell makes me sick.
