Heat a good glug of olive oil in your best 25/26cm frying pan over a low-medium heat. One that's non-stick. Once hot, place the grated potato into the frying pan, use a spatula to tidy up the edges and gently pat down the top into an even layer (don’t pack it tightly at this point). Cook for 10-12 minutes on the first side, checking halfway through that the potato isn’t browning too quickly, until the bottom is deeply golden and crisp.
Place a plate on top of the rosti and flip the pan to flip the rosti onto the plate. Add a glug more oil into the pan, then slide the rosti back into the pan, to cook the second side for 10-12 minutes, or until deeply golden and crisp.
