Why it works: Orange and sugar are a kitchen classic. They rank in the top 20% of all ingredient pairs, and 19,212 recipes mention both. Both carry beta-damascenone, which smells apple, rose. The science ↓
Orange Jelly Filling
Ingredients
Directions
Make the filling
Grate the oranges and the rind of one orange, then remove the seeds.
In a double boiler, combine the grated oranges, sugar, and water.
Mix the cornstarch with a little water and stir it into the orange mixture.
Cook until the raw taste of the starch is gone.
Remove from heat and fold in the beaten egg whites and powdered sugar.
Finish and use
Reserve some frosting for the top of the cake.
Stir the remainder into the orange mixture when it is cold.

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 moisture for the filling.
- Sugar
- Sweetens the filling and helps it thicken into a spreadable texture.
- Cornstarch
- Thickens the orange mixture as it cooks, giving the filling body.
- Egg whites
- Beaten and folded in to lighten the filling and add airy structure.
The step that matters
Cook until the raw taste of the starch is gone. Cornstarch must be heated fully to swell and thicken properly; undercooked starch leaves a raw, floury taste and a weak, thin texture.
