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 Jelly
Ingredients
Directions
Prepare the juice
Wipe the oranges and cut them in half.
Place the oranges in a saucepan with the water and boil for about 45 minutes.
Strain the juice from the mixture.
Bring the juice to a boil and let it boil for a few minutes.
Make the jelly
Measure the juice and add ¾ pound of sugar for each pint of juice.
Combine the juice and sugar in a preserving pan and boil until it jellies when cooled.
If it does not set, boil longer.
Jar
Pour the jelly into small jars and cover when cool.

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 juice along with natural pectin and acidity that help the jelly set.
- Lump sugar
- Adds sweetness and, once dissolved and boiled, helps the jelly set and keeps it preserved.
- Lemons
- Add extra acidity and pectin to support the setting of the jelly.
The step that matters
Boiling until it jellies. The jelly sets only when enough sugar, pectin and acid are concentrated by boiling. Stopping too early leaves a runny result, so test by cooling a spoonful and boil longer if it does not set.
