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

What each ingredient does

Potatoes
Provide starch and body, so the dough holds together and stays tender when mashed.
Flour
Gives the mashed potato mixture structure so the rounds keep their shape while boiling.
Blackberries
Add moisture and tart sweetness inside the dumplings as they cook.

The step that matters

Drop the filled rounds into boiling water and cook for 30 minutes. The water must be at a full boil when the dumplings go in so the dough sets quickly and does not absorb water or fall apart. Keeping the water boiling steadily through the cooking time helps the dumplings cook evenly.

Swap the potato

How well each one fits the dish's main ingredients (flour, sauce):

  1. Shallotfits better
  2. Arrowrootfits better
  3. Horseradishfits better
  4. Potatothe original

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