I love jacket potatoes, with lots of cheese and butter in it and crunchy skin. Yum!
I also like roast potatoes, when they're crispy yet mushy at the same time. Goes lovely with a roast dinner and thick gravy.
I don't like sweet potato because it tastes like parsnips and I really do not like parsnips. The taste of them makes me gag. I'm not normally that sensitive to tastes but something about the taste of parsnips my taste buds just don't like lol.
I like mash potatoes, although I think it constipates me up sometimes. I like it with spaghetti hoops or ravioli and sausages to dip into it.
New potatoes I'm not too keen on, or boiled potatoes. It tastes too starchy.
