Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the custard as they set with heat, giving it a rich, smooth body.
- Flour
- Stabilizes the custard so it thickens without curdling or becoming runny.
- Milk
- Forms the liquid base of the custard and carries the flavor and moisture.
- Sugar
- Adds sweetness and helps soften the custard's texture.
- Butter
- Adds fat for a richer flavor and smoother mouthfeel.
The step that matters
Stir the egg mixture into the boiling milk. Egg yolks can scramble if they meet very hot milk too quickly. Adding the mixture while stirring constantly and keeping the heat controlled lets the yolks thicken the custard smoothly instead of turning grainy.
