Cut your unpeeled potatoes into quarters boil or steam, let them cool slightly then the skins will just slip off and you can pop the potatoes into the ricer.
it would be quicker to peel the potatoes than fuss about picking skins out of a ricer-or even easier use frozen mash -its lovely with added butter and milk.
For a family it's often easier to just crush the boiled potatoes a little then layer them in a tray with a light drizzle of oil and seasoning and crisp up in the oven.
Lumps or bits will not go down well so I will peel them. Put off doing so as I have new (v sharp knives (no, don’t have a peeler, never used one) and I’m doing the whole bag of spuds).
Made a rod for my own back with the ricer - they know if I haven’t used it. The mash I’m doing is for ‘stick to the ribs cheesey mash’ (it’s mostly cheese) so I can’t use mamy’s method.
