But, children's taste buds are different from adults. Iirc they taste things more strongly, so the bitter notes are more pronounced.
Also, they've been breeding stuff like brussel sprouts to be less bitter for a while now, so veggies might actually taste better than when we were kids.
Same with Brussel sprout. My step-dad would boil them. Tastes like a soggy sulfur fart. But cut them in half, toss them in a bit of oil, salt and pepper, roast them until crispy in the oven with, and they're delicious. Oddly sweet, even. Try with other seasonings to enhance further.
Some might say that it makes them less healthy, but a very light drizzle of honey before you cook them, and it becomes one of the best things you'll ever eat
I love steamed (not boiled) asparagus. Though for most of my life, vegetables were just a vehicle for butter and salt. I’ve pulled way back on how much I use in recent years.
My buddy makes the most delicious grilled asparagus. He’s a real pro and it’s a treat to bbq with him.
I dunno about asparagus, but it turns out the Brussel sprouts we ate as kids were bitter and didn't taste as good as the ones they sell now. But yeah, with asparagus, you gotta broil those bad boys with garlic/olive oil, etc
