Why it works: Milk and butter 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 ↓
Chestnut 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
Make the peanut milk by dissolving the peanut butter in water and cooking it in a double boiler for one hour.
Preheat the oven to 350°F (175°C).
Beat the egg in a bowl.
Make the filling
Add the chestnuts, peanut milk, sugar, and salt to the beaten egg and mix well.
Bake
Pour the mixture into a pie crust and bake until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Binds the filling and helps it set into a firm custard when baked.
- Chestnuts
- Provide the body and starchy, mild bulk of the filling.
- Sugar
- Adds sweetness and helps the filling set smoothly.
- Peanut milk
- Supplies liquid and a nutty flavour that carries the custard.
The step that matters
Baking until set. Egg proteins coagulate as the filling heats, so the pie must bake until just set; overbaking can make it curdle, weep and turn rubbery.
Swap the chestnut
How well each one fits the dish's main ingredients (peanut, milk, egg, sugar, butter):
- Almondfits better

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