Why it works: Apple and lemon are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 7,551 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Apple Sauce
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
Pare, halve, and quarter the apples.
Place the apples in a baking dish.
Cover the apples thickly with sugar.
Add bits of lemon peel if desired.
Cover the dish with a plate.
Bake
Set the covered dish in a pan with a little hot water in the bottom.
Bake in a hot oven at 400°F (200°C) until the apples are clear and tender.

Apple and sugar barely smell alike, yet cooks put them together in 16,478 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
- Break down during baking to form the soft, sauce-like body of the dish.
- Sugar
- Sweetens the apples and draws out their juices, adding moisture to the sauce.
- Lemon peel
- Adds a bright aroma that balances the sweetness of the apples and sugar.
The step that matters
Covering the dish and setting it in water. The covered dish and water bath trap steam and keep the oven heat gentle, so the apples cook through and soften evenly without drying or scorching.
Swap the lemon
The recipe marks lemon as optional. How well each one fits the dish's main ingredients (apple, sugar):
- Pearfits better
- Vanillafits better
- Apricotfits better
- Lemonthe original
Fit is the average pairing score against apple, sugar. Candidates are from the same food group and used in at least 100 recipes.
