I never used to like them very much. I particularly disliked the way they could harbour gravy, producing a squelchy effect when you bit into them.
I'm moderately keen now - they seem sweeter and less squelchy than they were, although this is probably just the effect of me being older and having fewer taste buds. I did them for Christmas lunch lightly boiled and served with chopped chestnuts, which is nice.
My favourite way to do them is not to boil them at all, but to slice them into three (like small mushrooms) and stir fry them very quickly with onion, ginger, chilli, soy sauce, tiny bit of brown sugar, pak choi and cashews. That goes less well with roast spuds though.
