Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the milk as they set, giving the custard a firm, smooth body.
- Milk
- Provides the liquid base and creamy richness that the custard sets from.
- Coffee
- Adds the main coffee flavor and aroma to the infused milk.
- Loaf sugar
- Sweetens the custard to taste.
The step that matters
Cook until the custards are firm. Egg yolks set through gentle heat; overcooking forces the proteins to tighten and curdle, leaving a grainy, weeping texture. Cook gently in the water bath and stop once the custards just hold their shape.
