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 ↓
Baked Apples
Ingredients
Directions
The book says “a moderately hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Wash and wipe the apples, then cut out the cores and remove all seeds and dark spots.
Place the prepared apples in a granite or earthenware dish.
Fill and bake
Fill each apple with 1/2 to 1 teaspoon of sugar and add a bit of lemon peel.
Pour boiling water into the dish until it's about 1/4 inch deep.
Bake in a moderate oven at 350°F (175°C) until the apples are perfectly soft, which can take from 30 minutes to 2 hours depending on the type of apple.

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
- Provide the main body of the dish; their flesh softens and turns tender as they bake.
- Sugar
- Adds sweetness and helps the cooked apple flesh taste rounded and full.
- Lemon peel
- Adds aromatic oils that brighten the flavor of the sweet apple.
The step that matters
Baking until perfectly soft. Apples vary widely in density and juiciness, so cooking time can range from 30 minutes to 2 hours. Test for tenderness with a knife rather than relying on the clock, because underbaked flesh stays firm and overbaked apples collapse.

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