Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
Blueberry Cream Pie
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Make the filling
Beat the egg yolks in a bowl.
Add sugar, blueberries, lemon juice, flour, salt, and thick cream; mix well.
Pour the mixture into a pie plate lined with pastry.
Top and bake
In another bowl, beat the egg whites until stiff, then gradually add powdered sugar.
Spread the meringue over the pie filling.
Bake in a slow oven at 300°F (150°C) until the meringue is delicately 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 enrich it, helping it set as it bakes.
- Blueberries
- Provide the main fruit flavor and juice that moistens the filling.
- Flour
- Stabilizes the filling so it holds its shape when sliced.
- Thick cream
- Adds richness and a smooth, creamy texture to the filling.
- Egg whites
- Whip into a stiff foam that forms the meringue topping and browns in the oven.
- Powdered sugar
- Dissolves easily into the whipped whites, stabilizing the meringue and sweetening it.
The step that matters
Baking the meringue until just delicately brown. Meringue needs gentle heat to set and brown without weeping or toughening. Slow oven heat dries the surface evenly, and overbaking can make it shrink, weep, or turn leathery.
