Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Butter Scotch 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).
In a bowl, mix brown sugar, egg yolks, butter, and flour until smooth.
Make the meringue
In another bowl, beat the egg whites until soft peaks form.
Gradually add powdered sugar to the egg whites and continue beating until stiff peaks form.
Bake
Spread the meringue over the pie filling.
Bake in the preheated oven until the meringue is golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the filling and add richness and colour to the custard base.
- Egg whites
- Whip into a foam that forms the meringue topping.
- Brown sugar
- Adds sweetness and caramel-like butterscotch flavour to the filling.
- Flour
- Helps thicken the filling so it holds its shape when sliced.
- Butter
- Adds fat for richness and smooth texture in the filling.
The step that matters
Beating the egg whites to stiff peaks. Egg whites must be whipped until stiff and glossy so the meringue holds its shape and browns evenly. Under-beaten whites collapse, while sugar added too quickly can slow foaming.
