The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Gelatine
Sets the wine and lemon liquid into a firm jelly that holds its shape.
Egg yolks
Thicken the milk into a custard and add richness.
Cream
Adds lightness and richness to the custard when folded in whipped.
Wine
Adds flavour and acidity to both the jelly and the custard.
Milk
Forms the base of the custard, giving it body and softness.

The step that matters

Pour the custard into the space left by the small mould. The custard must be thick enough to hold its shape but still pourable. If the gelatine has set too far or the custard is too cold, it may not fill the gap cleanly or may leave air pockets against the jelly.

Swap the lemon
