IME (And I do generally start eating sprouts once the are available, and continue to do so until they are no longer for sale) they do absolutely NOT need cross cutting to cook well. Probably 15 minutes is about optimal, not boiled to soggy mush but not crunchy raw. It's a fine balance.
Sprouts+fennel=0farts
Fresh sprouts are not available where I live, so the only ones I've ever eaten were frozen or canned. I wasn't all that enthusiastic about them, but they were a nice change on occasion.
Over the last year I've bought several different brands, frozen or canned, and they all have a weird taste, like a cross between "iron" and bitter. The old ones just tasted like cabbage.
Most people don't seem to notice, so it either happened gradually or long enough ago they don't remember.
So should many of us 😉(I should put that last bit on my signiture!!!)
My late MiL would put the sprouts on to boil first thing in the morning when she put the turkey in the oven.
