I have a friend coming round for lunch tomorrow and her favourite summer meal is potato salad… I've cubed and I'm boiling some Cyprus potatoes but they won't do will they? I have to do it tonight because tomorrow morning is mental and I'll be busy right up until she arrives… I wondered if I boil them "only just" and then chill them (dry) in the fridge… And dress just before serving? Or should I just parboil them and stick them in the fridge in bang them in the oven with some olive oil tomorrow instead?
