Ingredients:
- 4 large Russet or Idaho potatoes (approx. 900g / 2 lbs)
- Cold water for soaking and rinsing
- 30g / 2 tablespoons Unsalted Butter, clarified (or Ghee)
- 30ml / 2 tablespoons Neutral Oil (e.g., canola, vegetable, or peanut oil)
- 5g / 1 teaspoon Sea Salt
- 1/2 teaspoon Freshly Ground Black Pepper
- 1/4 teaspoon Onion Powder (optional)
Instructions:
- Peel the potatoes and grate them coarsely, using either the large holes of a box grater or a food processor attachment.
- Rinse Thoroughly: Immediately transfer the grated potatoes to a large bowl and cover them with cold water. Swish them around, drain, and repeat the rinse process 3–4 times until the water runs mostly clear to remove excess surface starch.
- Soak (Optional): Allow the rinsed potatoes to sit in cold water for 10 minutes, then drain completely.
- Squeeze and Dry (THE Critical Step): Transfer the wet potatoes to the center of a clean kitchen towel or strong cheesecloth. Twist tightly and squeeze out as much liquid as possible. The potatoes must be thoroughly dry.
- Season: Transfer the thoroughly dried potatoes to a clean, dry bowl. Toss immediately with salt, pepper, and onion powder (if using). Seasoning just before cooking prevents the salt from drawing out more moisture.
- Form: Gently form the seasoned potato mixture into a large, loose patty or two smaller patties, depending on the size of your pan. Do not pack them too tightly; a slightly looser structure allows for better crisping.
- Heat the Fat: Place the heavy-bottomed skillet (cast iron recommended) over medium-high heat. Add the clarified butter and neutral oil. Wait until the fat is shimmering and highly mobile.
- Lay the Patty: Carefully slide the potato patty(s) into the hot fat. Immediately reduce the heat to a steady medium.
- Cook the First Side: Allow the hashbrown to cook undisturbed for 8–10 minutes. Use a spatula to peek underneath; the bottom should be deep golden brown.
- Flip: Once the bottom is perfectly colored, use a sturdy spatula to flip the hashbrown in one swift motion.
- Finish Cooking: Cook for another 8–10 minutes until the second side matches the first and the center feels heated through.
- Drain and Serve: Remove the hashbrowns and place them briefly on a wire rack or a paper towel-lined plate to drain any excess fat. Serve immediately.
