  1. Preheat the water bath to a temperature of 80⁰C.
  2. Toss the grated potato with the salt, then place in a colander and set aside to drain. The salt will draw out the starchy water in potato.
  3. After 15 minutes, wrap the potato in a clean, dry tea towel. Twist the tea towel until you cannot squeeze out any more moisture, then transfer the potato to a mixing bowl.
  4. Heat the duck fat in a small saucepan until completely melted. Tip the molten fat into the bowl with the grated potato and stir until thoroughly combined, then seal the mixture in a large vacuum bag using a chamber sealer.
  5. Place the bag in the water bath and cook for 4 hours.
  6. Once cooked, leave the potato to cool inside the vacuum bag. When it has cooled completely, unseal the bag, remove the rösti and divide into 8 portions. You can make the portions any shape you choose.
  7. Melt some duck fat in a frying pan, add the portions of rösti and fry, turning as necessary, until golden brown and crispy all over.
