We took our favorite latke recipe and cooked it as one large pancake in a skillet. Cut the finished product into wedges and serve with a delicious assortment of fun toppings, like whitefish salad or applesauce.
Peel the potatoes and grate them on the large holes of a box grater into a colander set over a large bowl. Grate the onion into the colander and season with 1 teaspoon salt and 1/2 teaspoon pepper. Firmly squeeze the potatoes and onion to extract as much liquid as possible, letting it drain into the bowl. Transfer the potato mixture to a separate large bowl. Add the egg and matzo meal or flour and stir well.
Heat a medium cast-iron or other heavy-bottomed skillet over medium heat. Add the oil or chicken fat and heat until shimmering. Add the potato mixture and press down with a spoon or spatula to make an even layer. Cook until deep golden brown and crisp on the bottom, 8 to 10 minutes. (After a few minutes, check to make sure the latke is browning evenly and rotate the latke in the skillet as needed. If it’s sticking, loosen it with a small spatula.)
Carefully slide the latke onto a plate using a wide spatula. Flip the latke on the plate, then quickly slide it back into the skillet, cooked-side up. Continue cooking until well browned on the second side and cooked through, 8 to 10 more minutes. (Lower the heat as needed if the latke is browning too quickly.) Remove the latke to a paper towel–lined plate and sprinkle with salt.
Wipe out the skillet and return the latke to the skillet or transfer to a cutting board. Slice into wedges and serve with assorted toppings.
