Why it works: Flour and nutmeg are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 18,623 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Buttermilk 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
In a mixing bowl, combine sugar, egg, buttermilk, butter, and flour.
Stir the mixture well until fully combined.
Flavor the mixture with nutmeg to taste.
Bake
Pour the filling into the pie crust.
Bake in the preheated oven until set.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Egg
- Sets the custard-like filling as it bakes and adds richness and structure.
- Buttermilk
- Provides tangy acidity and moisture, giving the filling its characteristic tang and smooth body.
- Sugar
- Adds sweetness and helps the filling brown lightly at the edges.
- Flour
- Thickens the filling slightly so it holds together when sliced.
The step that matters
Bake until set. Egg proteins coagulate as the filling heats, turning liquid into a firm custard. Underbaking leaves it runny, while overbaking can make it curdle or crack.
Swap the nutmeg
How well each one fits the dish's main ingredients (sugar, egg, buttermilk, butter, flour):
- Cinnamonfits about as well
- Nutmegthe original
- Jalapenofits about as well
- Capersfits less well
Fit is the average pairing score against sugar, egg, buttermilk, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
