A potato side worth slowing down for
Llapingachos are Ecuadorian potato patties with cheese tucked inside and a browned exterior. They make a satisfying side for a larger meal, but they are substantial enough to anchor a plate of salad and other accompaniments. The appeal is the contrast: a lightly crisp surface, tender potato and a warm, savory center.
The trickiest part is not the filling. It is getting the potato mixture firm enough to shape while keeping it soft enough to eat. Wet potatoes can slump or split in the pan; potatoes packed too tightly can turn dense. A little attention to moisture, temperature and handling makes the process much more forgiving.
Start with a firm, smooth potato mixture
For about eight modest patties, start with roughly two pounds of potatoes. Peel them, cut them into similar-size pieces and simmer in salted water until a fork passes through easily. Drain thoroughly, then return the potatoes to the warm, empty pot for a minute or two, stirring gently so excess steam can escape. Mash while warm, breaking up lumps without working the potatoes until they become gluey.
Season the mash with salt and a little ground cumin if you like. You can also soften finely chopped onion in a small amount of oil and fold it in. Let the mixture cool until it is comfortable to handle. It should hold a mound on a spoon and feel pliable rather than sticky. If it seems loose, give it more time to cool before adding anything else. If it seems dry and crumbly, a small splash of milk or water may help it come together.
Different potatoes release different amounts of moisture, so treat the texture as your guide. Avoid adding a large amount of liquid or oil to the mash: you want it supple enough to seal around the cheese, not so soft that it spreads when heated.
Fill, seal and rest the patties
Divide the cooled potato mixture into eight portions. With lightly damp hands, flatten one portion into a thick disk in your palm. Place a small spoonful of grated or finely crumbled melting cheese in the center, leaving a clear border of potato around it. Bring the edges up over the cheese and pinch them closed, then gently flatten the parcel into a patty about three-quarters of an inch thick.
Keep the filling modest. Too much cheese pushes against the seams as it warms and creates openings where it can leak into the pan. If a crack appears while you shape a patty, press a little reserved potato over it and smooth the join. Aim for an even thickness and rounded edges rather than squeezing the patty thin.
Set the shaped patties on a plate or tray and refrigerate them for at least 20 minutes. This rest firms the potato and makes the patties easier to lift and turn. Keep them covered if they will be in the refrigerator longer, and return any cheese you are not using to the refrigerator promptly.
Brown gently and turn only once
Warm a thin film of oil in a heavy skillet over medium heat. Add a few patties at a time, leaving enough room to slide a spatula underneath each one. Let the first side cook undisturbed until it has formed a golden crust and releases without resistance, then turn it carefully with a broad spatula. Brown the second side and check that the center is heated through and the cheese has softened.
If the exterior darkens before the middle warms, lower the heat. If a patty sticks, wait a little longer rather than pulling it free; the crust may not have formed yet. Pressing down with a spatula can force the filling out, so resist the urge to flatten the patties in the pan. A small cheese leak is not a failure, but a sealed patty and a gentle turn will help keep more of the filling inside.
Cook in batches rather than crowding the skillet. Hold finished patties on a plate while the rest brown, and serve them warm for the best contrast between crust and center.
Build a bright, balanced plate
Llapingachos pair well with crisp vegetables and something tangy. Try a simple salad of thinly sliced red onion, tomato and shredded lettuce, dressed just before serving with lime juice, a little oil and salt. Sliced avocado and a spoonful of mild tomato-onion salsa are other welcome additions. Keep wet toppings beside the patties until serving so their browned surfaces stay intact.
For an easy meal, prepare the potato mixture and shape the patties ahead, then keep them refrigerated until you are ready to cook. Wash hands and utensils after handling ingredients, keep perishable fillings chilled, and refrigerate leftovers promptly. Rewarm leftover patties in a skillet over moderate heat, turning gently, to refresh the exterior without crushing the potato.
