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 ↓
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 the filling
Preheat the oven to 350°F (175°C).
Beat the egg yolks.
Add the brown sugar, flour, and a little cold milk.
Cook the mixture in a double boiler until thick.
Add a pinch of salt.
Assemble and bake
Bake a pie shell as you would for a lemon cream pie.
Pour the thick mixture into the baked shell.
Beat the egg whites with a little sugar until stiff.
Spread the meringue on top.
Brown the meringue slightly in the oven.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the custard filling, and whites whip into the meringue topping.
- Brown sugar
- Adds sweetness and the caramel-like butterscotch flavor to the filling.
- Flour
- Thickens the filling so it sets firm when cooked and cooled.
- Butter
- Adds richness and fat for flavor and a smooth texture in the filling.
The step that matters
Cook the filling until thick. Egg yolks and flour thicken the filling as it heats, but overheating can scramble the eggs and make the custard grainy. Cooking gently in a double boiler and stirring keeps it smooth before it is poured into the shell.
