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).
Line pie tins with the pie crust.
Make the filling
In a bowl, combine buttermilk, egg yolks, butter, flour, and sugar. Mix well.
Pour the buttermilk mixture into the crust.
Bake in the preheated oven until set.
Add the meringue
Beat the egg whites until stiff peaks form.
Spread the beaten egg whites on top of the pie.
Return the pie to the oven to brown the meringue.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Buttermilk
- Provides tangy acidity and moisture that gives the filling its custard-like body.
- Egg yolks
- Set during baking to thicken the filling into a sliceable custard.
- Butter
- Adds fat for richness and a smooth, tender texture in the filling.
- Flour
- Thickens the filling and helps it hold its shape as it sets.
- Sugar
- Sweetens the filling and helps it set into a smooth, firm texture.
- Egg whites
- Whipped to stiff peaks to form the airy meringue topping that browns in the oven.
The step that matters
Bake the filling until set. Underbaking leaves the egg-thickened filling runny, while overbaking can make the egg proteins curdle and weep, so the filling should just firm up before the meringue goes on.
Swap the nutmeg
How well each one fits the dish's main ingredients (buttermilk, egg, butter, flour, sugar):
- Cinnamonfits about as well
- Nutmegthe original
- Jalapenofits about as well
- Capersfits less well
Fit is the average pairing score against buttermilk, egg, butter, flour, sugar. Candidates are from the same food group and used in at least 100 recipes.
