Not necessarily. Individual expression of TAS2Rs is genetically determined and varies considerably[1]; and so the perceived bitterness of sinigrin-containing vegetables like cabbage (B. oleracea) differs from person to person [2,3].

Apparently I've never cooked any of those properly! Anyway, I'm sure everyone has a few least-favorite veggies that would clear up that sentence (unless they really dislike pancake batter).

Almost any vegetable tastes amazing sautéed in butter with shallots and garlic. You can also add plain breadcrumbs once done. I say this having just made brussel sprouts that way for dinner. Very simple and very delicious. And I used to hate brussel sprouts.

Brussel sprouts used to be more bitter than they are; farmers have actively been breeding better tasting brussels sprouts. Lots of people who used to hate them and didn't eat them for a number of years find them more pleasant when trying them now.
