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 yolks
Thicken the custard and add richness through their fat and emulsifying proteins.
Egg whites
Add airiness and help give the set custard a light, tender texture.
Gelatin
Sets the custard so it holds its shape when unmolded.
Thin cream
Adds fat and richness, giving the custard a smooth, soft texture.
Sugar
Adds sweetness and helps soften the set texture of the custard.

The step that matters

Cooking the custard in the double boiler. Egg yolks thicken as they warm, but if the heat is too high they can curdle or scramble. Gentle, indirect heat keeps the custard smooth while it thickens.
