Why it works: Peach and pineapple match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 168 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Custard Pie
Ingredients
Directions
The book says “a very slow oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the custard
Preheat the oven to 350°F (175°C).
In a bowl, combine milk, 5 eggs, and 8 tablespoons sugar.
Pour the mixture into pie crusts and bake until set.
Make the fruit filling
In a saucepan, combine mashed peaches, grated pineapple, and 3 tablespoons melted butter.
Simmer until thick, then cool and stir in 6 beaten egg yolks.
Pour the fruit mixture into the baked pie crusts.
Top and brown
In a separate bowl, beat 6 egg whites until stiff, then gradually add 3 tablespoons sugar and flavoring.
Spread the meringue over the pies and brown in the oven for 20 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the custard and thicken the fruit filling, while whites whip into a meringue.
- Milk
- Provides the liquid base that sets into a soft custard with the eggs.
- Sugar
- Sweetens the custard and meringue and stabilizes the whipped egg whites.
- Peaches
- Add fruit flavor and moisture to the filling.
- Pineapple
- Adds tart, fruity flavor and moisture to the filling.
- Butter
- Adds richness and fat to the fruit filling.
The step that matters
Simmer the fruit mixture until thick. The fruit must be cooked down enough to thicken before the egg yolks are stirred in. Adding yolks to a hot mixture can scramble them, and a loose filling will make the pie runny once it sets.
Swap the pineapple
How well each one fits the dish's main ingredients (milk, egg, sugar, peach, butter):
- Vanillafits better

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