Why it works: Sugar and vanilla are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Filling for Cream Cake
Ingredients
Directions
Make the custard
Place the cream in a small saucepan and set it in another pan with boiling water.
Mix the corn starch with a little cold milk and stir it into the cream.
Cook until it boils for 2 minutes, then add the sugar.
Beat the egg yolks with a spoonful of cold milk and stir it in.
Finish and fill
Remove from heat and beat the egg whites with ½ teaspoon of sugar until stiff, then fold them in.
Add the vanilla extract and let it cool before filling the cakes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweet cream
- Provides the rich, fluid base that the filling sets from.
- Corn starch
- Thickens the cream as it heats, giving the filling body.
- Egg
- Yolks add richness and thickening; whipped whites lighten the filling.
- White granulated sugar
- Sweetens the filling and helps stabilise the whipped whites.
- Vanilla extract
- Adds aroma that rounds out the sweetness of the filling.
The step that matters
Stirring in the egg yolks. Yolks can scramble if they meet a very hot mixture. Adding them off the boil and stirring steadily lets them thicken the filling smoothly instead of forming lumps.
