About this saved recipe
Ingredients
- 11 oz Maris Piper potato
- 0.16 oz sea salt
- 0.21 oz potato starch
- 2 tbsp neutral oil
- 0.71 oz butter
Instructions
- 1Grate the potatoes on the coarse side of a box grater. Immediately toss with the sea salt, cover, and let rest 10–15 minutes to draw out moisture.
- 2Transfer the grated potatoes to a clean tea towel or muslin cloth. Gather the edges and squeeze firmly until no liquid is released; the drier the potatoes, the crispier the roasti.
- 3Place the dried potatoes in a bowl, sprinkle the potato starch over them, and toss thoroughly so the starch coats the strands evenly.
- 4Heat the neutral oil in a 20 cm non‑stick frying pan over medium heat.
- 5Add the potato mixture to the pan, spreading it into an even round. Press gently with a spatula to level the surface without compacting it too firmly; leave small gaps for steam to escape.
- 6Cook for 8–10 minutes, adjusting the heat as needed, until the underside is deeply golden and crisp.
- 7Slide the roasti onto a plate, place the pan upside‑down over the top, then invert the whole assembly so the uncooked side drops back into the pan.
- 8Add the butter around the edges; when it foams, tilt the pan and continuously baste the roasti with the butter for another 6–8 minutes until both sides are golden and crisp.
- 9Transfer the roasti to a cooling rack for 1–2 minutes, finish with freshly ground black pepper, and serve immediately.
