Consider the warm comfort of knish

If you’re looking for some cold weather comfort food, you might want to consider the knish.

Though there are many variations of the knish, they essentially are the hand pie of classic Jewish cuisine — a baked (though sometimes fried) light pastry dough filled with mashed vegetables (often potatoes) or meat. They started as peasant food, later became a 19th century street cart convenience food, and now are a staple of Jewish delis.

They can be hard to find if you don’t live in a larger city. But whether or not you’re Jewish, consider making some this winter. They are warm and filling and truly satisfying in that way that only carb-heavy food can be.

Potato knishes

3eggs, divided

6tablespoons vegetable or canola oil, divided

1/2cup water

1tablespoon cider vinegar

Kosher salt

21/2cups all-purpose flour

4pounds russet potatoes, peeled and cubed

2large yellow onions, diced

1/4cup chopped fresh thyme

Ground black pepper

In a large bowl, whisk together 2 eggs, 2 tablespoons of the oil, the water, vinegar and 1/2 teaspoon of salt. Add the flour and knead together to form a smooth dough. Divide the dough in 2 and wrap each piece tightly in plastic wrap. Refrigerate for 1 hour.

While the dough chills, prepare the filling. Place the potatoes in a medium saucepan and fill with enough water to cover by 1 inch. Bring to a boil, then reduce to a simmer. Simmer until the potatoes are tender, 12 to 15 minutes. Drain thoroughly, then transfer the potatoes to a medium bowl. Mash the potatoes until mostly smooth. Set aside.

In a medium skillet over medium-high, heat the remaining 4 tablespoons of oil. Add the onions and cook until tender and starting to brown, about 8 minutes. Stir the onions into the potatoes, along with the thyme. Season with salt and black pepper.

Heat the oven to 375 degrees. Line a baking sheet with kitchen parchment.

Working with one piece of dough at a time, roll and stretch each piece until it is a long strip about 6 inches wide and 16 inches long. Spoon half of the potato filling mixture down the middle of each strip of dough, using your hands to smooth the mixture into an even mound. Dip your fingers in water and moisten the edges of the dough, then wrap both sides of the dough up and over the potato filling.

Slice each piece of dough, which now should resemble filled tubes, into 8 pieces. Turn each piece onto its side and use the palm of your hand to flatten slightly. Working in batches of 8, arrange the pieces on the prepared baking sheet, leaving about 1 inch between them.

In a small bowl, beat the remaining egg with 1 tablespoon of water until foamy. Brush a bit of the egg mixture over each knish. Bake for 30 minutes, or until deep golden brown. Let cool for 10 minutes before serving.
