Egg and cream barely smell alike, yet cooks put them together in 42,166 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Egg yolk
Sets into a firm, tender custard as it heats and its proteins coagulate.
Cream
Adds richness and fat, giving the custard a softer, smoother texture.
Water
Dilutes the egg so the custard stays moist and sets more gently.

The step that matters

Bake until firm. Egg proteins set gradually with gentle heat. Overbaking forces them to tighten and squeeze out water, leaving the custard grainy and weeping. The water bath moderates the heat, so the custard should be removed once it is just firm.
