I hope you got on with it - I notice I am too late for tea tonight, but for another time, I like it done two ways -
firstly, skin on, cut into 'roast potato' size chunks, frilighted and into the oven / 200deg / 30 - 45 mins. Secondly as a soup - peel and chunk, place in a pan with a stock cube, water, chopped onion and maybe a chopped chilli (or some ground cumin is nice if you don't like spice), when it's soft (25mins) I blitz it into a lovely, creamy, smooth soup.
