Why it works: Flour and butter 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 ↓
Baked Apple Dumplings
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the dumplings
Mix flour and butter until crumbly.
Roll out the dough.
Cut the dough into circles the size of a coffee saucer.
Place four quarters of apples in the center of each dough circle.
Fold the edges over to seal.
Bake the dumplings at 400°F (200°C) for one hour.
Make the sauce
Combine sugar, cornstarch, butter, vinegar, and salt in a saucepan and mix well.
Pour in boiling water while stirring briskly.
Boil the sauce for twenty minutes.
Add lemon extract.
Serve
Place the baked dumplings on a platter.
Pour the sauce over them.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Forms the dough structure that holds the apples while baking.
- Butter
- Adds fat that keeps the dough tender and helps it turn crumbly.
- Apples
- Provide the filling, softening and turning sweet and tender as they bake.
- Sugar
- Sweetens the sauce and balances the vinegar's sharpness.
- Cornstarch
- Thickens the sauce as it heats and boils.
- Vinegar
- Adds acidity that brightens the flavor of the sweet sauce.
The step that matters
Boil the sauce fully while stirring. Cornstarch only thickens once it reaches a full boil. Stirring while adding the boiling water keeps the starch dispersed so it does not clump, and boiling for the full time gives a smooth, properly thickened sauce.
Swap the lemon
How well each one fits the dish's main ingredients (flour, butter, apple, sugar, vinegar):
- Pearfits better
- Figfits better
- Vanillafits better
- Lemonthe original
Fit is the average pairing score against flour, butter, apple, sugar, vinegar. Candidates are from the same food group and used in at least 100 recipes.
