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 ↓
Orahgb Marmalade
Ingredients
Directions
Prepare the peel
Grate the rinds of the Seville oranges lightly.
Cut the grated rinds into quarters, removing the flesh.
Use a small spoon to remove the pips and loose inner skin from the flesh.
Soak the rinds in cold water overnight.
Boil the rinds for 20 minutes, changing the water halfway.
Once tender, drain the rinds.
Slice the rinds thin.
Make and jar the marmalade
Add 8 ounces of rinds for each pound of pulp and juice.
Add 1.5 pounds of sugar.
Boil the mixture quickly for 30 minutes, skimming as needed.
Pour the marmalade into jars.

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 peel and pectin-rich pulp give the marmalade its bitter flavour and set.
- Sifted sugar
- Sweetens the marmalade and helps it set when boiled with the fruit.
The step that matters
Boil the mixture quickly for 30 minutes. Rapid boiling drives off water and concentrates the sugar and pectin so the marmalade sets. Skimming removes scum that would cloud it.
