If you've never had a pierogi, allow me to describe it to you: it's like a cheesy, potato-y, onion-y ravioli that is seared in butter. These things are, in a word, heaven. Not all pierogi are made with potatoes--some are made with sauerkraut, and some with fruit. In our house, we like the potato ones best. Here, we've used purple sweet potatoes (available at Whole Foods) and purple onion to make for a colorful surprise inside the little dumpling. It also makes for a slightly sweet foil to the sourness of the sauerkraut. You can use any kind of potato you want here. Get creative and make it your own.
Purple Potato Pierogi 1 1/2 cups peeled, chopped purple potato (about 1 medium) 3 tablespoons unsalted butter (divided) 1 1/4 cups finely diced diced purple onion (about 1 medium) 1/4 cup white wine (like Pinot Grigio) 1 cup shredded sharp white cheddar Kosher salt and cracked black pepper (to taste) Pierogie Dough (recipe follows) 1 cup vegetable broth (like Whole Foods 365 brand) Sauerkraut, sour cream, and chives to garnish Boil the potato in salted water until tender (about 8 minutes), drain, and set aside in a large bowl. In a medium frying pan over medium heat, melt 1 tablespoon of the butter and cook the onion until translucent and starting to brown. Deglaze the pan with the wine and cook until most of the liquid has evaporated. Add the onion to the potato and mash until no large pieces of potato are left; you want it to have some texture. Fold in the shredded cheese and add salt and pepper to taste. Roll the dough out using your pasta maker on a number 5. Alternately, roll the dough out using a rolling pin to get the dough just about as thin as possible. Place 1 heaping tablespoon about 1/2 inch apart, fold the dough over, and cut a half-moon shape using a fluted pasta wheel. Continue until all the dough and filling has been used. You can re-roll the scraps and use those if you have more filling to use. Makes about 24 pierogi.
Bring a large pot of salted water to a boil, and in a separate 12-inch frying pan, melt 1 tablespoon of butter over low heat. Boil 12 of the pierogi for about 3 minutes, crank the heat under the butter to high, transfer the boiled pierogi to the buttered pan; allow them to cook undisturbed for 2 to 2 1/2 minutes for a nice sear. Add 1/2 a cup of the vegetable broth and flip the pierogi using a pair of tongs. Repeat this process with the remaining pierogi or freeze them for another day. Serve the pierogi of a bed of warm sauerkraut garnished with a dollop of sour cream and a sprinkling of chives. Spoon the pan sauce created with the broth and butter around the plate.
