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 ↓
Red Apples in Jelly
Ingredients
Directions
Prepare the apples
Pare and core the apples, placing them in water to prevent browning.
In a preserving pan, add the apples with just enough water to half cover them.
Cook the apples
Coddle the apples, turning them when the lower part is done, ensuring they are not too close together.
Mix pounded cochineal with the water and boil with the fruit.
Once cooked, place the apples stalk down on a serving dish.
Make the jelly and serve
Make a jelly with the cooking water, loaf sugar, lemon rind, and juice, boiling until it sets.
Let the jelly cool, then pour it over the apples and garnish with narrow strips of lemon peel.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Hold their shape during cooking and provide the fruit that is set in the jelly.
- Loaf sugar
- Sweetens the jelly and helps it set when boiled.
- Lemon
- Its juice adds acidity and its rind adds aroma to the jelly.
- Pounded cochineal
- Colours the cooking liquid and the jelly red.
The step that matters
Coddle the apples without crowding them. Apples cooked too close together or boiled too hard can break or cook unevenly. Turning them when the lower part is done lets heat reach all sides so they keep their shape.
