Flour and butter barely smell alike, yet cooks put them together in 124,287 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
- Egg
- Thickens the filling as it cooks and gives it a rich, set custard body.
- Flour
- Thickens the filling so it holds its shape rather than running.
- Sugar
- Sweetens the filling and helps balance the tartness of the citrus.
- Orange juice
- Adds liquid and bright orange flavour to the filling.
The step that matters
Cooking in a double boiler while stirring. Egg and starch thicken as they heat, but egg proteins can curdle or scorch if the mixture gets too hot. Gentle indirect heat and constant stirring keep the filling smooth and evenly thickened.
Swap the orange
How well each one fits the dish's main ingredients (sugar, flour, lemon, egg, butter):
- Raisinfits better
- Vanillafits better
- Figfits about as well
- Orangethe original
Fit is the average pairing score against sugar, flour, lemon, egg, butter. Candidates are from the same food group and used in at least 100 recipes.
