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 ↓
To Preserve Oranges in Jelly
Ingredients
Directions
Prepare the oranges
Cut a hole at the stalk of the oranges.
Scoop out the pulp.
Tie the oranges in muslin.
Soak them in spring water for two days, changing the water twice daily.
Boil the oranges in muslin until tender.
Add hot water as needed to keep covered.
Weigh the oranges.
Make the syrup
For every pound, use two pounds of sugar and one pint of water.
Boil the sugar and water with the orange juice to make syrup.
Skim well.
Let it cool.
Add the oranges to the syrup and boil for half an hour.
Repeat daily for two to three days if not clear.
Make the green pippin jelly
Prepare green pippins by peeling and coring them.
Boil until the water is strong with apple flavor without stirring.
Strain the water through a jelly bag until clear.
Add one pound of sugar and lemon juice for every pint of water, boiling to a strong jelly.
Pot and seal
Drain the oranges from the syrup.
Place them in jars with holes upward.
Pour the jelly over them.
Cover with brandy papers.
Tie securely.

Sugar and lemon 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 and pulp that become the preserved fruit and its flavor.
- Double refined sugar
- Sweetens and, at high concentration, helps the syrup and jelly set and keep.
- Green pippins
- Their natural pectin and acid help the water set into a firm jelly.
- Juice of a lemon
- Adds acidity that supports pectin setting and brightens the flavor.
The step that matters
Boiling the green pippin water to a strong jelly. Apples must be boiled long enough to extract pectin, and the sugar must then be boiled to the right concentration. Undercooked jelly stays runny, while overcooking can make it stiff or cloudy.
