Why it works: Grape and sugar are a kitchen classic. They rank in the top 23% of all ingredient pairs, and cooks put them together in 7,490 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
“Shaddock” or “Grape-Fruit” Marmalade
Ingredients
Directions
Prepare the fruit
Peel the fruit and shred the rind very thin.
Remove all the seeds and skin from the oranges.
Place the seeds and skin in a basin with half the water.
Put the rind and pulp in another basin with the remaining water and let stand for 24 hours.
Strain the water from the seeds and skin.
Add the strained water to the water with the rind.
Cook and set
Boil until the rind is tender.
Let it stand until the next day.
Add 1½ pounds of sugar for every pound of fruit and water.
Boil until it jellies well.

Shared aroma: beta-damascenone (apple, rose).
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shaddock or seville oranges
- Provides the bitter peel and pulp that give marmalade its characteristic flavor and pectin for setting.
- Lump sugar
- Sweetens the marmalade and, once boiled, helps it set into a firm jelly.
The step that matters
Boil until it jellies well. Sugar and pectin only set when enough water has evaporated and the mixture reaches the right concentration. Undercooking leaves a runny marmalade, while overcooking can make it stiff and dull in flavor.
