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 ↓
Chocolate Cream 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 crust
Preheat the oven to 350°F (175°C).
Line a small pie plate with pastry.
Bake until golden.
Make the filling
Heat the milk in a saucepan.
Blend the cornstarch and sugar with the beaten egg in a bowl.
Add the mixture to the heated milk and cook until thick.
Stir in the melted chocolate until well combined.
Pour the chocolate filling into the baked crust.
Let it cool.
Finish and serve
Cover the pie with whipped cream just before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base that thickens into the custard filling.
- Unsweetened chocolate
- Gives the filling its chocolate flavour and deep colour.
- Cornstarch
- Thickens the milk mixture as it cooks, giving the filling its set.
- Egg
- Adds richness and helps bind and thicken the custard.
- Sugar
- Sweetens the filling and balances the bitterness of the chocolate.
The step that matters
Cooking the filling until thick. Cornstarch must reach a simmer and cook for a while to swell and thicken fully. Undercooked starch leaves the filling thin and runny, and it will not set properly as it cools.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
