I can not get cauliflower past my epiglottis. It's the only food that causes me to have a gag reflex. I've tried it every way I can and no dice. It has some musty, earthen taste that's just anathema to me. I've given up on them totally.
I know what you mean about brussel sprouts, too. I must say, however, I finally had some that were evidently prepared well and I actually enjoyed them.
