Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Add richness and thicken the filling as it sets in the oven.
- Egg whites
- Beaten stiff, they trap air that lightens the filling and helps it rise.
- Sugar
- Adds sweetness and helps soften the butter when creamed.
- Butter
- Adds fat for a rich, tender texture.
- Oranges
- Juice supplies tartness and rind supplies fragrant citrus aroma.
The step that matters
Fold in the beaten egg whites. Folding gently keeps the air bubbles in the stiff whites. Stirring or deflating them makes the pie denser and less light after baking.
Swap the orange
How well each one fits the dish's main ingredients (sugar, butter, egg):
- Vanillafits better
- Lemonfits better
- Raisinfits better
- Orangethe original
Fit is the average pairing score against sugar, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
