Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the custard as they cook, giving it structure and a firm, sliceable texture.
- Milk
- Adds moisture and richness, producing a creamy texture once set.
- Sugar
- Sweetens the custard and helps balance the bitterness of the coffee.
- Strong coffee
- Provides the main flavour of the custard.
The step that matters
Bake until set. Eggs set gradually as they heat, and overbaking can make the custard curdle, weep liquid, or turn rubbery. Check for a set centre that still jiggles slightly.
“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.
