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 ↓
Sugar 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 a pie pan with the pie crust.
Place the butter pieces on the crust.
Make the filling
Sprinkle the sugar over the butter.
Strew the flour over the sugar and mix well.
Add enough water to wet the mixture without dissolving it, leaving about 2-3 tablespoons of water unabsorbed.
Grate nutmeg over the top.
Bake
Bake until golden brown.

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 helps it caramelise to a golden top as it bakes.
- Butter
- Adds richness and fat that keeps the filling tender and helps it brown.
- Flour
- Thickens the sugar and butter mixture so it sets rather than running.
- Water
- Moistens the mixture so the sugar and flour bind into a crumbly, custard-like layer.
The step that matters
Adding the water. Water must wet the mixture without dissolving the sugar fully. Too much water makes the filling runny and soggy, while too little leaves the flour dry and pasty.
Swap the nutmeg
How well each one fits the dish's main ingredients (butter, sugar, flour):
- Cinnamonfits better
- Jalapenofits better
- Nutmegthe original
- Capersfits less well
Fit is the average pairing score against butter, sugar, flour. Candidates are from the same food group and used in at least 100 recipes.
