• Pantry: Neutral oil, fine sea salt, white pepper, flaky sea salt (optional)

Full Ingredients

For the råraka (potato rösti)

• 600 g starchy potatoes (Russet, King Edward, or similar), peeled
• 60 g clarified butter, divided (about 4 tbsp total)
• 1 tbsp neutral oil (rapeseed/canola or sunflower)
• 1 tsp fine sea salt
• 1/4 tsp finely ground white pepper

Toppings

• 100 g Kalix löjrom (Kalix bleak roe), well chilled
• 120 ml full-fat crème fraîche (about 8 tbsp), well chilled
• 1 small red onion (50 g), finely diced
• 2 tbsp finely snipped chives (about 6 g)

To serve

• 1 lemon, cut into 4 wedges
• Flaky sea salt, to finish (optional but recommended)

Step-by-Step Instructions

Step 1: Chill and prep the garnishes

Keep the löjrom and crème fraîche refrigerated until plating. Finely dice the red onion; for a gentler flavor, soak the diced onion in ice water for 5 minutes, then drain and pat dry. Snip the chives and cut the lemon into wedges. Set aside in the fridge.

Step 2: Grate and dry the potatoes

Peel the potatoes and grate them on the coarse side of a box grater. Toss with 1 tsp salt and let sit for 3 minutes to draw out moisture. Gather the grated potatoes in a clean kitchen towel and squeeze very firmly until no more liquid drips out—the drier, the crisper the råraka. Sprinkle in the white pepper and toss. If you collected any potato liquid, allow it to sit for 1 minute; a small amount of white starch settles at the bottom—scrape up about 1 tsp and mix back into the potatoes for extra binding.

Step 3: Preheat the pan

Set a heavy 24–26 cm skillet (cast iron or high-quality nonstick) over medium-high heat for 2 minutes. The ideal surface temperature is about 190°C/375°F. Add 10 g clarified butter (about 2 tsp) plus just enough neutral oil to lightly film the pan. Swirl to coat.

Step 4: Fry the first side

Spread one quarter of the potato (about 150 g) into a 14–16 cm disc, about 5 mm thick. Neaten the edges with a spatula, but do not press hard—loose strands at the perimeter become the lacy, crisp edge. Cook undisturbed for 3–4 minutes until the underside is deep golden and the edges look frilly and browned.

Step 5: Flip and finish

Slide a wide spatula underneath and flip confidently. Add 5 g clarified butter (about 1 tsp) around the edges and tilt the pan to let it run under the råraka. Cook 2.5–3.5 minutes more until the second side is crisp and the center is tender. Transfer to a wire rack set over a baking sheet and keep warm in a 95°C/200°F oven. You will use a total of 15 g clarified butter per pancake (10 g first side + 5 g after flipping), equaling 60 g for all four.

Step 6: Repeat

Repeat Steps 3–5 for the remaining three rårakor, adding a thin film of oil only as needed to prevent scorching. Adjust heat to keep the butter gently sizzling but not smoking.

Step 7: Plate and garnish

Place each råraka on a warm plate. Top with 2 tbsp (about 30 ml) crème fraîche and 25 g löjrom. Scatter a small spoonful of diced red onion and a pinch of chives over each. Finish with a tiny pinch of flaky sea salt and serve immediately with a lemon wedge for squeezing.

Pro Tips

• Use clarified butter for high-heat frying without burning milk solids; it delivers pure buttery flavor and a clean, crisp finish.
• Bone-dry potatoes are the secret—wring them out hard. Any extra moisture softens the crust.
• Keep the pancakes thin (about 5 mm). Too thick and they steam instead of crisping.
• Rest cooked rårakor on a wire rack in a low oven (95°C/200°F) to stay crisp—never stack them.
• For extra binding, add a teaspoon of settled potato starch (or 1 tsp cornstarch) back into the grated potatoes.

Variations

• Roe swap: If Kalix löjrom is unavailable, use quality whitefish roe or salmon roe. Taste and reduce finishing salt accordingly—roe is naturally salty.
• Canapé size: Make 8–12 mini rårakor (5–6 cm). Cook 1.5–2 minutes per side. Top each with 1 tsp crème fraîche, 1 tsp roe, a few onion cubes, and chives.
• Dill-forward: Replace half the chives with finely chopped dill. Finish the second side with a small knob (5 g) of regular butter for a nutty aroma in the last 30 seconds.

Storage & Make-Ahead

Rårakor are best fresh. You can hold finished pancakes on a wire rack in a 95°C/200°F oven for up to 30 minutes. To re-crisp leftovers, refrigerate on parchment up to 2 days, then bake on a rack at 220°C/425°F for 5–7 minutes. Keep roe and crème fraîche well chilled; once opened, roe is best within 24–48 hours. You can grate potatoes up to 1 hour ahead and store submerged in cold water with 1 tsp white vinegar to prevent browning—drain, dry extremely well, and add 1 tsp potato starch or cornstarch if needed for binding before frying.
