@Gnometorious @acorn I keep them simple. Grate some potatoes, mandolin a white onion. Bundle them both together in a tea towel and drain out as much water as possible. Add an egg, salt and pepper and mix. Then heat up a decent amount of veg/sunflower oil in a pan. bung in a spoonful of the mix, press it out to flatten it, flip when it’s brown.
For potato cakes mix old mash, an egg, a bit of flour, a bit of cheese and I like a diced onion and some herbs. Dollop into hot oil and press it out , let it cook into shape and flip after a few minutes
