Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Tomato Dumplings
Ingredients
Directions
Prepare the tomato base
Combine the can of tomatoes, butter, and sugar in a pot and bring to a hard boil.
Make the batter
Mix the flour, baking powder, and salt in a bowl; gradually add cold water to form a stiff batter.
Cook the dumplings
Drop spoonfuls of the batter into the boiling tomatoes and continue to boil rapidly.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the body of the dumplings, giving them structure as they cook.
- Baking powder
- Releases gas that makes the dumplings rise and turn light and fluffy.
- Tomatoes
- Provide the liquid and acidity that form the sauce the dumplings cook in.
- Sugar
- Balances the acidity of the tomatoes with sweetness.
- Butter
- Adds fat for richness and a smoother flavor to the sauce.
The step that matters
Keep the tomatoes at a rapid boil when adding the batter. Dropping the batter into a gentle simmer can make the dumplings heavy and soggy. A rapid boil sets the outside of each dumpling quickly, helping it hold its shape and cook through in the steam and liquid.
Swap the tomato
How well each one fits the dish's main ingredients (walnut, butter, sugar, flour):
- Shallotfits better
- Beetrootfits better
- Sweet potatofits better
- Tomatothe original
Fit is the average pairing score against walnut, butter, sugar, flour. Candidates are from the same food group and used in at least 100 recipes.
