I wonder whether it's a genetic thing, like sprouts taste bitter to some people or summat.
I mean I love cauliflower, it's one of my favourite veggies, it has a lovely nutty flavour and I will happily eat it just steamed or even raw. That is enhanced if roasted (and the last time I did cauli cheese I roasted the cauli a bit first and it was absolutely divine).
N can't stand cauli, others say it has no flavour, I just don't get either of those positions tbh.
Just want to add to the above, cauli in curry - nothing quite like an aloo gobi.
