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 ↓
Pickled Apples
Ingredients
Directions
Prepare the apples
Pare the apples and boil them until tender in a syrup made of 4 pounds of sugar and 1 quart of vinegar.
Remove the apples from the syrup.
Make the spiced syrup
Boil the 3 large lemons until tender.
Slice the boiled lemons.
Make a new syrup with 5 pounds of sugar, 1 quart of vinegar, ½ ounce of mixed spices, and the sliced lemons.
Boil this syrup for half an hour.
Pour the hot syrup over the fruit.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweet apples
- Form the main body of the pickle, softening as they simmer in the syrup.
- Sugar
- Sweetens the pickle and, with the vinegar, helps preserve the fruit.
- Vinegar
- Adds acidity that sharpens the flavour and helps preserve the fruit.
- Lemons
- Add acidic citrus flavour and aroma to the syrup.
The step that matters
Boil the apples until tender in the syrup. Apples must be cooked through so they take up the syrup, but over-boiling can make them mushy and break them apart. Testing for tenderness with a fork helps keep them whole.
Swap the lemon
