Why it works: Bread and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Swiss Apple Pudding
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).
Pare and slice the apples.
Layer and bake
Butter a baking dish and sprinkle a little bread crumbs and sugar on the bottom.
Layer the sliced apples on top, continuing until the dish is full.
Finish with a top layer of bread crumbs and sugar.
Dot the top with small pieces of butter.
Place the dish in a pan of hot water and bake for about 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Provide the main body and tart flavour as they soften under the crumbs.
- Bread crumbs
- Form a soft, absorbent layer that holds moisture from the apples and sugar.
- Butter
- Adds richness and helps the top brown lightly as it melts.
- Sugar
- Sweetens the dish and helps the apples caramelise slightly at the edges.
The step that matters
Place the dish in a pan of hot water. The water bath moderates the heat reaching the dish, so the apples cook through gently without the crumbs scorching before the fruit softens.
Swap the apple
How well each one fits the dish's main ingredients (bread, sugar, butter):
- Vanillafits better
- Figfits better
- Applethe original
- Peachfits about as well
Fit is the average pairing score against bread, sugar, butter. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
