Instructions
Instructions
- Set air fryer to 200 °C.
- Squeeze grated potato through a clean fine cloth or muslin (or a clean tea-towel will work too), getting out as much excess water as possible (you should be left with approx. 350g after the water has gone).
- In a bowl, add the squeezed out grated potato and butter, mix well.
- Weigh into 25g portions for canapes and 50g portions for a side.
- Once they are all portioned, press together into little discs, keeping some ragged bits/texture.
- Add the Crispy Roast Potato sachet to a shallow bowl and toss each rosti in the seasoning.
- Then in another shallow bowl, coat the rosti with the olive oil.
- Place evenly spaced out in air fryer and cook for 10 minutes, turn over and put back in for another 5 minutes for canapes, or another 10 mins if you’re making side-sized rosti.
- To serve, sprinkle with a little black pepper and any desired toppings such as crème fraiche and smoked salmon or grated roasted beets.
