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 ↓
Steamed Apples
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.
Prepare
Preheat the oven to 400°F (200°C).
In a bowl, mix flour, butter, and baking powder until crumbly.
Fill a pie plate with the quartered apples.
Cover the apples with the prepared crust.
Cook and serve
Steam or cook on the stove until the apples are tender.
Transfer to the oven to brown the crust.
Serve with your preferred sauce.

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
- Apples
- Provide the fruit base, and their tartness balances sweetness while they release moisture as they steam.
- All-purpose flour
- Forms the structure of the crust once it is mixed with the butter.
- Butter
- Adds fat that makes the crust tender and helps it brown in the oven.
- Baking powder
- Releases gas that lifts the crust, giving it a lighter texture.
The step that matters
Cook the apples until tender before browning the crust. Oven heat mainly browns the crust and does not soften dense fruit well. If the apples are still firm when they go in, they will stay underdone while the top darkens.
Swap the apple

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