Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Jelly Pies
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Make the filling
In a bowl, cream together the butter and sugar.
Add the flour and mix well.
Stir in the jelly until combined.
Beat the egg whites until stiff, then fold in the yolks.
Gently combine the egg mixture with the jelly mixture.
Bake
Fill a pastry shell with the mixture and bake until set.

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
- Eggs
- Whites trap air for lift, and yolks add richness and help the filling set.
- Plum jelly
- Provides fruit flavour, sweetness and moisture to the filling.
- Sugar
- Sweetens the filling and creams with butter to give a lighter texture.
- Flour
- Adds structure that helps the filling hold together once baked.
- Butter
- Adds fat for richness and a tender texture.
The step that matters
Gently combine the egg mixture with the jelly mixture.. Egg whites hold air bubbles that give the filling lift. Stirring vigorously knocks that air out, so the pie bakes denser and flatter. Fold slowly to keep the air in.
Swap the plum
How well each one fits the dish's main ingredients (egg, sugar, flour, butter):
- Raisinfits better
- Vanillafits better
- Figfits better
- Plumthe original
Fit is the average pairing score against egg, sugar, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
