Why it works: Orange and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 10,634 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓
Florida Orange Marmalade
Ingredients
Directions
Prepare the fruit
Grate the yellow rind of 9 large oranges.
Remove the thick white rind from the grated oranges and from 9 more oranges.
Free the pulp and juice of the oranges from all the white skin.
Weigh the 18 oranges.
Measure out an equal weight of white sugar.
Cook the marmalade
Add the grated rind and the juice of 3 large lemons to a pot.
Add the grated rind, lemon juice, and sugar to the pot.
Bring the mixture to a boil.
Add the pulp and juice to the boiling mixture.
Boil the marmalade slowly until a small amount jellies when cooled on a saucer.

Lemon and sugar barely smell alike, yet cooks put them together in 53,532 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
- Oranges
- Provide the bitter peel, pulp and juice that form the marmalade's flavour and body.
- Lemons
- Add extra acidity and natural pectin that help the marmalade set.
- White sugar
- Sweetens the marmalade and, with the fruit's pectin and acid, helps it gel.
The step that matters
Boil until the marmalade jellies. Boiling drives off water and concentrates the sugar and pectin. Testing a small amount on a cold saucer shows whether it will set; boiling too briefly leaves it runny, while overcooking can make it stiff and dull.
