Why it works: Plum and vanilla match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 171 recipes. Both carry methyl cinnamate, which smells strawberry. The science ↓
Caramel Pie
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the filling
Cream together the sugar and butter.
Add the milk, eggs, preserves, and vanilla; mix well.
Bake
Pour the mixture into single pie crusts.
Bake in a moderate oven at 350°F (175°C) until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Sweetens the filling and browns slightly in the oven for a caramel-like flavor.
- Butter
- Adds richness and fat, giving the filling a tender, smooth texture.
- Eggs
- Set as they bake, turning the liquid filling into a firm, custard-like pie.
- Milk
- Adds moisture and creaminess to the filling.
- Damson plum preserves
- Add tartness and fruit flavor that balances the sweetness.
- Vanilla
- Adds a warm, aromatic flavor to the filling.
The step that matters
Bake until set. Eggs set as they heat, so the filling needs enough time to firm up. Overbaking can make it curdle or weep liquid, while underbaking leaves it runny in the center.
Swap the plum
How well each one fits the dish's main ingredients (sugar, butter, milk, egg, vanilla):
- Figfits better

- Coconutfits better
- Plumthe original
Fit is the average pairing score against sugar, butter, milk, egg, vanilla. Candidates are from the same food group and used in at least 100 recipes.
