Why it works: Chocolate and sugar are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 15,404 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
Chocolate 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.
Make the filling
Combine milk, cornstarch, egg yolks, and grated chocolate in a saucepan.
Sweeten to taste.
Cook over medium heat until thickened.
Pour the chocolate mixture into a pre-baked pie crust.
Frost and bake
Whip the egg whites until stiff peaks form.
Spread the whipped egg whites over the pie when cool.
Place the pie in a 350°F (175°C) oven.
Brown the frosting slightly.

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 of the custard filling.
- Cornstarch
- Thickens the milk mixture as it heats, giving the filling body.
- Egg yolks
- Add richness and help set the custard filling.
- Grated chocolate
- Gives the filling its chocolate flavor and color.
- Egg whites
- Whipped into a meringue topping that gives a light, airy frosting.
The step that matters
Cook over medium heat until thickened. Cornstarch only thickens fully when the mixture reaches a boil and is stirred, so undercooking leaves a thin filling. Heating the egg yolks too hard or too fast can curdle them.
“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.
