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.
Place the apples in water.
Add the apples to a preserving pan with enough water to cover them halfway.
Ensure the apples are not too close together.
Cook the apples
Coddle the apples.
Turn the apples when the lower side is done.
Mix the pounded cochineal with water and boil the mixture with the fruit.
Make the jelly and serve
Place the cooked apples stalk down on a serving dish.
Make a rich jelly with the cooking water, loaf sugar, lemon rind, and juice.
Allow the jelly to cool.
Pour the cooled jelly over and around the apples.
Cut the lemon peel into narrow strips and place the strips across the eye of each 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
- Well-shaped apples
- Hold their shape during coddling and form the body of the dessert.
- Loaf sugar
- Sweetens the jelly and helps it set when the syrup cools.
- Lemon
- Its juice adds acidity to balance the sugar and its rind adds aroma.
- Pounded cochineal
- Provides the red colour that tints the apples and jelly.
The step that matters
Using minimal cochineal. Too much cochineal makes the colour dark and the flavour bitter, so the tint should be kept light and vibrant from the start.
Swap the lemon
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.
