Scrub the potatoes well. Grate them with the onion either using a box grater or the grating attachment on a food processor.
1 kg starchy potatoes, 1 medium onion
Add the grated vegetables to a large bowl and mix with the eggs, flour, salt, nutmeg, and pepper flakes (optional).
2 large eggs, 120 grams flour, 2 teaspoons sea salt, ¼ teaspoon freshly ground nutmeg, ¼ teaspoon hot pepper flakes
Heat a large frying pan over medium heat (cast iron is ideal). Once the pan is hot, add enough oil to just cover the bottom.
Oil for frying
Fry spoonfuls of potato pancake mixture, about two tablespoons per piece, until golden brown on the bottom. This takes about two minutes. Flip, press to flatten, and cook the other side until golden brown and crisp.
Repeat until the whole mixture has been used. You can make the pancakes bigger, but don't make them too thick or else they won't cook through.
Serve hot with applesauce and any other desired toppings. Leftovers can be refrigerated for a couple of days and freeze well.
Notes
This serves between four and six, depending on what you're offering alongside.
