" POTATO PIEROGI Makes 65 to 70 pierogi; 8 to 10 servings This recipe…yields a large amount. You could halve the recipe, but instead I recommend making the full amount and freezing half. Frozen pierogi can be dropped directly into boiling water for cooking; there’s no thawing required. You can also refrigerate the dough for a day or two, so you can make the pierogi in a couple batches. PIEROGI WRAPPERS • 1 large egg yolk • 1 cup whole milk • 1 tablespoon vegetable oil • 3 ¼ cups all-purpose flour "
