- 4 large Maris Piper potatoes, scrubbed, not peeled
- 2 beetroot, peeled, coarsely grated
- 2 cloves garlic, crushed
- salt and freshly ground black pepper
- 5 tbsp olive oil
- 100g/3½oz fresh horseradish
- 200g/7oz crème fraîche
- 1 lemon, juice only
- salt and freshly ground black pepper
- 250g/10½oz smoked salmon
- 8 sprigs fresh dill, to serve
- 4 lemon wedges, to serve
- Place the potatoes into a saucepan of boiling salted water and boil for seven minutes, then drain and leave to cool.
- When the potatoes are cool enough to handle, peel them and grate them into a bowl.
- Add the grated beetroot and garlic, season, to taste, with salt and freshly ground black pepper, and mix together well.
- Divide and shape the potato mixture into six flat patties, place onto a baking sheet and transfer to the fridge to chill for one hour.
- Heat the oil in a large frying pan over a medium-high heat. Add the potato röstis and fry for 4-6 minutes on each side, or until golden-brown all over, then drain on kitchen paper.
- For the horseradish sauce, mix the horseradish, crème fraîche and lemon juice together in a clean bowl and season, to taste, with salt and freshly ground black pepper.
- To serve, place each rösti onto a plate. Top with a spoonful of horseradish sauce and a piece of salmon, then finish each plate with some sprigs of dill and a lemon wedge.
