Memorable Knishes Recipe
- 2 cups all-purpose flour
- 1 teaspoon baking powder
- ½ teaspoon salt
- 2 tablespoons vegetable oil
- 2 eggs, lightly beaten
- 2 tablespoons melted chicken fat (schmaltz) or vegetable oil
- 2 cups finely chopped onions
- 2 cups plain mashed potatoes
- Salt and freshly ground black pepper, to taste
- To make the dough: Combine the flour, baking powder, and salt in a large bowl. Make a well in the center and add the oil, eggs, and 2 tablespoons water. Gradually mix the wet ingredients with the flour. Add up to 2 tablespoons more water if necessary. Knead the dough until it forms a rough ball.
- Knead the dough on a lightly floured surface until the dough is smooth, about 6 minutes. Place the dough in a lightly oiled bowl, cover, and refrigerate for 1 hour.
- Preheat the oven to 350°F.
- To make the filling: Combine the chicken fat, onions, potatoes, and salt and pepper to taste in a bowl.
- Remove the dough from the refrigerator and divide it into thirds. On a floured surface, roll out one piece of the dough into a thin rectangle about 10 inches long. Spread about 2/3 cup of the filling along one long end, about 1 inch from the edge. Roll up like a jelly roll and pinch the edges closed. Repeat with the remaining pieces of dough and filling.
- Arrange the rolls on baking sheets. Bake until browned, about 40 minutes.
- Slice the knishes and serve.
