glucosinolates - that’s the compound I was thinking of which tastes bitter to some people, and has no flavor at all to others. Genetic.
Kind of like now asparagus quickly changes the odor of urine. Many people can’t smell the change and others are very sensitive to it. I’m in the latter camp.
“Asparagusic acid, as the name implies, is (to our knowledge) only found in asparagus. When our bodies digest the vegetable, they break down this chemical into a group of related sulfur-containing compounds with long, complicated names (including dimethyl sulfide, dimethyl disulfide, dimethyl sulfoxide and dimethyl sulfone).”
