When I was growing up my mother always cooked Brussel sprouts. It was so strong. I liked them and got accustomed to the taste of them. I haven't had them since my mother cooked them when I lived at home. I knew my children would be turned off by this so I never thought about cooking them for my family.
I searched and found how not to have that strong taste. I was correct about the strong taste was caused by overcooking them. I know that happens with broccoli if it overcooked. My teenage daughter does not like overcooked broccoli since it makes her stomach feel weird. I have learned to cook them just to the point before that strong taste comes. Yes, you learn lots with picky children.
