Why it works: Orange and sugar are a kitchen classic. They rank in the top 20% of all ingredient pairs, and cooks put them together in 19,212 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Orange-Jelly
Ingredients
Directions
Prepare the juice and peel
Cut each orange in half and squeeze the juice through a silk sieve into a dish.
Rub the peel of 3 oranges on a lump of sugar to extract flavor, then scrape off the yellow part.
Make the jelly
Break ½ pound of sugar into small pieces and place in a pan.
Beat the egg white with water until frothy and add to the sugar.
Heat the mixture until it begins to bubble, then pour in the orange juice.
Skim off any yellow scum that forms, then strain through a jelly bag.
Boil 1 ounce of isinglass in ¾ pint of water for 2 hours, then mix with the jelly when nearly cold.
Set
Pour the jelly into a mould and refrigerate until set.

Orange and sugar barely smell alike, yet cooks put them together in 19,212 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
- Isinglass
- Sets the juice into a firm jelly as it cools.
- Egg white
- Whipped with water, it helps clarify the syrup by trapping impurities that are skimmed off.
- Sugar
- Sweetens the jelly and helps give it body.
- Oranges
- Provide the juice and flavor, with peel oils adding aroma.
The step that matters
Skim off the yellow scum before straining. Impurities rise to the surface as the mixture heats. Removing them before straining keeps the jelly clear and free of bitter or off flavors.
Swap the orange
How well each one fits the dish's main ingredients (sugar, egg):
- Vanillafits better
- Raisinfits better
- Lemonfits better
- Orangethe original
Fit is the average pairing score against sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
