The choice of toppings, dipping sauces, and garnishes depends on the filling. Generally, savoury pierogi are coated in butter (or oil) and generously sprinkled with sautéed onions, bacon lardons, and/or pork cracklings. Freshly chopped herbs, such as parsley or dill, are also a popular choice. A dollop of thick sour cream serves as the most classic dip. Meat-filled pierogi pair wonderfully with sweet and sour fruit preserves, such as cranberry or prune jam/sauce. Sweet-filled pierogi are sprinkled with sugar (either caster/superfine or powdered) and served alongside lightly sweetened sour cream. Fruit-based sauces and preserves complement them beautifully as well. You can discover more pierogi sauce ideas here.
