Why it works: Buttermilk and flour are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 3,721 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓

Flour and butter 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
- Egg
- Binds the batter and helps give the dumplings structure as they set.
- Buttermilk
- Adds moisture and tang, and its acidity reacts with the baking soda.
- Baking soda
- Reacts with the buttermilk's acidity to produce gas that lightens the batter.
- Flour
- Forms the stiff batter's structure, which sets around the apple as it cooks.
- Apple
- Provides fruit flavor and moisture inside each dumpling.
The step that matters
Steam until cooked through. The batter must set fully in the steam. Undercooked flour and egg stay gummy and dense, so the dumpling needs enough time over steady boiling water.
Swap the apple
How well each one fits the dish's main ingredients (egg, buttermilk, flour, butter):
- Raisinfits better
- Vanillafits better
- Lemonfits better
- Applethe original
Fit is the average pairing score against egg, buttermilk, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
