Sauerkraut Pierogi Filling

Time15 minutes

Ingredients

Directions

Prepare the sauerkraut

  1. Place sauerkraut and liquid in a pot with enough water to cover the sauerkraut and bring to a boil.

  2. Remove from stove and transfer to a colander.

  3. Drain and rinse the sauerkraut well with cold water to prevent further cooking.

  4. Squeeze as much liquid from the kraut as possible with your hands to prevent sogginess.

  5. Place the sauerkraut on a large cutting board and chop finely with a large, flat-bladed knife.

Make the filling

  1. Fry the onion until translucent.

  2. Add the drained sauerkraut.

  3. Season with salt and pepper to taste.

  4. Simmer for 15 minutes.

  5. Let it cool before using.

  6. Refrigerate a few hours before using to fill pierogi.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Sauerkraut
Provides the sour, tangy flavour that defines the filling.
Onion
Adds sweetness and savory depth as it softens and turns translucent.
Butter
Adds richness and fat, carrying flavour through the filling.

The step that matters

Squeeze the sauerkraut dry. Excess liquid left in the kraut makes the filling wet and soggy, which can tear dough and dilute flavour. Squeezing removes this water before cooking and filling.

Swap the onion

How well each one fits the dish's main ingredients (butter, pepper):

  1. Capsicumfits better
  2. Potatofits better
  3. Carrotfits about as well
  4. Onionthe original

Fit is the average pairing score against butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
