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 ↓
Marmalade, Orange, Crated
Ingredients
Directions
Prepare
Grate the outer rind of the oranges and lemon.
Scoop out the insides and remove the seeds.
Bruise the pulp with ¼ cup of water through a sieve.
Weigh the orange pulp and measure out an equal weight of sugar.
Cook
Boil the orange pulp, sugar, and grated rind together until the rind is tender, about 30 minutes.
Soak the grated rind in water to prevent clumping before adding it to the mixture.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oranges
- Pulp and rind supply flavour, bitterness and pectin that help the marmalade set.
- Lemon
- Adds acidity and pectin, which help the marmalade set and keep its brightness.
- Sugar
- Sweetens the marmalade and helps it set and keep by drawing water away from the fruit.
The step that matters
Boil until the rind is tender. The rind must soften fully during boiling, because its thick peel stays chewy if undercooked. Pectin from the pulp and rind helps the mixture gel as it reduces with sugar.
