When boiled or parboiled potatoes are required I now substitute microwaving for boiling.
Potatoes are not peeled just scrubbed and dried then processed as required.
For roast potatoes around 5 minutes, allow to cool, after which skin should peel off early. Cut to size, place in an oiled dish, and roast as usual. Reslt is the best I have ever had.
For smashed potatoes 6-8 minutes then placed on a board and flattened using a folded tea towel. Season, oil, and roast as usual.
Mashed potatoes take around 8 minutes then left to cool and skin peeled off. Once peeled they are re-heated in the microwave for 1-2 minues after which I mash them in my mixer with butter, milk, salt, and pepper.
Times wll vary according to microwave, those work for me and there is no risk of scalding
