Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Jelly Pie
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
Beat together the egg yolks, sugar, flour, butter, and nutmeg in a bowl.
Stir in the milk until well combined.
Pour the mixture into a pie crust‑lined pan.
Bake and top
Bake until set and golden.
Once cool, spread jelly over the top.
Top with sweetened whipped cream or beaten egg whites.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the custard filling as they set in the oven, giving it structure and richness.
- Sugar
- Sweetens the custard and helps soften the set texture.
- Flour
- Stabilises the custard so it holds its shape when baked.
- Butter
- Adds fat for a richer, smoother texture in the filling.
- Milk
- Provides liquid that the egg proteins set into a custard.
The step that matters
Bake until set and golden. Egg-based custards continue to firm as they cool, but underbaking leaves a runny centre while overbaking can cause curdling, weeping and a cracked surface. Checking for a just-set centre prevents both problems.
Swap the nutmeg
How well each one fits the dish's main ingredients (egg, sugar, flour, butter, milk, cream):
- Nutmegthe original
- Cinnamonfits about as well
- Capersfits less well
- Jalapenofits less well
Fit is the average pairing score against egg, sugar, flour, butter, milk, cream. Candidates are from the same food group and used in at least 100 recipes.
