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 and add richness and a smooth texture.
- Flour
- Thickens the milk mixture so the custard holds its body.
- Butter
- Adds richness and a smooth mouthfeel to the custard.
- Whole milk
- Forms the liquid base that the yolks thicken into a custard.
- Vinegar
- Adds a touch of acidity that brightens the sweet custard.
The step that matters
Cook over low heat, stirring constantly, until thick. Egg yolks can curdle or scramble if overheated. Gentle heat with constant stirring lets the yolks thicken the custard evenly and smoothly.
