Why it works: Sugar and orange 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
Make the jelly
Boil the cow's heel in 2 quarts of water until tender and the water is reduced to 1 quart.
Strain the mixture and add sifted sugar and the juice of the oranges.
Add the egg whites and bring to a boil once more.
Clarify and set
Strain through a flannel bag into a mold and place in a cold area to set.

Sugar and orange 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
- Cow's heel
- Its collagen dissolves into the water and gives the jelly its body as it cools.
- Egg whites
- As they heat, they coagulate and trap impurities, clarifying the jelly for a clear result.
- Sugar
- Adds sweetness and balances the sharpness of the orange juice.
- Oranges
- Their juice supplies the flavor and acidity of the jelly.
The step that matters
Adding the egg whites and reboiling. The egg whites must be stirred through before the boil so they can coagulate and trap particles. Boiling too hard or stirring too late can leave the jelly cloudy.
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.
