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 ↓
Oranqb Marmalade
Ingredients
Directions
Cook the peel
Place the Seville oranges in a pan and cover them with water.
Boil gently for 3 hours.
Remove the oranges from the water and let them cool slightly.
Cut them into very thin strips, removing the seeds.
Make the marmalade
For every pound of fruit, add 2 pounds of sugar and ½ cup of the water used for boiling the oranges.
Dissolve the sugar in the water.
Add the fruit, rind, and juice of the lemons, and the juice of the sweet oranges.
Boil for 45 minutes until clear.

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
- Seville oranges
- Provide the bitter peel for flavour and natural pectin that helps the marmalade set.
- Sugar
- Sweetens the marmalade and, with heat and acid, helps it set into a gel.
- Lemons
- Add acidity and extra pectin, which help the marmalade set and brighten the flavour.
- Sweet oranges
- Add juice for sweetness and moisture, balancing the bitterness of the Seville oranges.
The step that matters
Final boil until clear. Pectin, sugar and acid form a gel only at a sufficient concentration and temperature. Boiling too briefly leaves the marmalade runny, while boiling too long can darken it and make it stiff.
