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 ↓
Baked Apples
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Wash and halve the tart apples, removing the cores.
Place the apple halves close together in a baking pan with a little water.
Fill and bake
Add 1 teaspoon of sugar and a small piece of butter to each half apple.
Lightly dredge the apples with flour.
Bake in a 400°F (200°C) oven until soft and lightly browned.

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
- Tart apples
- Provide the main body and tart flavour that sweetens as the apples cook.
- Sugar
- Adds sweetness and helps the cut surfaces brown in the oven.
- Butter
- Adds richness and moisture as it melts over the apple flesh.
- Flour
- Lightly coats the surfaces, helping them brown and thicken the juices.
The step that matters
Bake until soft and lightly browned. Apples can stay firm or scorch if underbaked or overbaked. Enough time lets the starches and cell walls soften, while watching the colour prevents the sugars from burning.
Swap the apple
How well each one fits the dish's main ingredients (sugar, butter, flour):

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