Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set and thicken the custard as they cook, giving the filling structure.
- Butter
- Adds richness and fat, giving the filling a smooth, tender texture.
- Flour
- Thickens the mixture so it holds its body when cooked.
- Chocolate
- Provides the main chocolate flavour and helps thicken the custard as it cooks.
- Milk
- Supplies liquid that cooks into the custard, adding softness and body.
- Sugar
- Adds sweetness and balances the bitterness of the chocolate.
The step that matters
Cooking the custard in a double boiler. Eggs can curdle or scramble if heated too quickly. Gentle, indirect heat lets the custard thicken smoothly to the right consistency before it goes into the crust.
“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.
