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 ↓
Jelly for Orange Cake
Ingredients
Directions
Prepare the orange mixture
Grate the rind of one orange and peel and grate both oranges.
Remove the seeds and add sugar and water to the grated oranges.
Cook and thicken
Scald the mixture in a tin pan set in a kettle of hot water.
Mix cornstarch with a few spoons of cold water until smooth, then stir into the orange mixture.
Cook just enough to cook the cornstarch.
Finish with frosting
When nearly cold, beat the egg whites and add powdered sugar for frosting.
Reserve some frosting for the top of the cake, then stir the rest into the orange mixture.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Oranges
- Provide the main flavor, aroma and acidity, along with the grated rind.
- Sugar
- Adds sweetness and helps give the jelly its body.
- Cornstarch
- Thickens the orange mixture as it cooks to a jelly-like set.
- Egg whites
- Whipped into the frosting, adding light structure and a glossy finish.
The step that matters
Cook just enough to cook the cornstarch. Cornstarch thickens when heated past its gelatinization point, but overcooking can break down its thickening power and make the jelly thin or pasty. Stop heating once the mixture has thickened.
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.
