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
Wash and scrub the oranges.
Take a few strips of peel from the deepest colored oranges.
Slice all the oranges and lemons; peel and pulp them, reserving the strips of peel.
Remove the pips and steep the pulp in 3 pints of water for 24 hours.
Steep the pips by themselves.
Make the jelly
Strain off the juice.
Boil all ingredients together for 2 hours.
Strain through a jelly bag.
Remove the strips of peel before pouring into the jelly bag.
Finish
Cut the strips very fine.
Add the finely cut peel to the jelly.
For each pound of juice, add 1½ lbs of loaf sugar.
Boil for 25 minutes and skim well.

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
- Their natural pectin and acidity help the jelly set and give a sharp flavor.
- Lemons
- Their acidity and pectin support setting and brighten the flavor.
- Sweet oranges
- They add sweetness, aroma and body to the juice.
- Loaf sugar
- Sweetens the jelly and, boiled with the juice, helps it set and keeps it preserved.
The step that matters
Boil for 25 minutes and skim well. Skimming removes foam and scum that would cloud the jelly. Boiling with the sugar concentrates the liquid so it can set properly.
