Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the mixture as they set with heat, giving it a rich, smooth body.
- Gelatine
- Sets the liquid mixture so it holds its shape when chilled.
- Orange juice
- Provides the main flavor and acidity that defines the jelly.
- Milk
- Adds creaminess and body to the base before it sets.
- Whipped cream
- Adds lightness and a soft, creamy topping at serving.
The step that matters
Thickening the egg yolks with the hot milk. Egg yolks scramble if they get too hot too fast. Stirring steadily while the mixture thickens keeps it smooth and prevents curdled specks.
Swap the orange
How well each one fits the dish's main ingredients (sugar, milk, cream, lemon, egg):
- Vanillafits better

- Orangethe original
- Figfits about as well
Fit is the average pairing score against sugar, milk, cream, lemon, egg. Candidates are from the same food group and used in at least 100 recipes.
