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 Custard Pie
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the custard
Simmer the milk in a saucepan.
Add the grated chocolate and sweeten to taste with sugar.
Beat in the well-beaten eggs until fully combined.
Bake and serve
Pour the mixture into the pie crust.
Bake in a moderately hot oven at 400°F (200°C) until set.

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 the eggs set into a creamy custard.
- Baker's chocolate
- Gives the custard its chocolate flavor and rich body.
- Eggs
- Set during baking to thicken the custard and hold its shape.
- Sugar
- Sweetens the custard and balances the bitterness of the chocolate.
The step that matters
Baking until set. Egg proteins thicken the custard as they heat. Underbaking leaves it runny, while overheating makes the eggs curdle and weep, so the custard should be removed once it is just set.
“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.
