Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Jelly Pie
makes three piesIngredients
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, stir together the egg yolks, sugar, and butter until well combined.
Add the milk (or cream), jelly, and vanilla extract to the mixture.
In a separate bowl, beat the egg whites until frothy, then gently fold them into the mixture.
Bake
Pour the mixture into pie crusts; this recipe makes three pies.
Bake in the preheated oven until set.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 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
- Yolks enrich and set the custard, while whipped whites add lightness and structure.
- Sugar
- Adds sweetness and helps tenderize the custard texture.
- Butter
- Adds fat for richness and a smooth, tender texture.
- Milk
- Provides liquid and body, and sets with the eggs to form the custard.
- Jelly
- Adds fruit sweetness, flavor, and moisture to the filling.
- Flour or cornstarch
- Thickens the filling so it holds its shape when baked.
The step that matters
Folding in the beaten egg whites. Whites must be frothy but not overbeaten, and folded gently so the air is kept. Deflating them makes the filling denser and less light after baking.
Swap the vanilla
How well each one fits the dish's main ingredients (egg, sugar, butter, milk, flour):
- Vanillathe original
- Raisinfits about as well
- Figfits less well
- Coconutfits less well
Fit is the average pairing score against egg, sugar, butter, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
