Why it works: Cream and butter are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Creme Patissiere, or Pastry Cream
Ingredients
Directions
Make the custard
Gradually add the beaten yolks of the eggs to the flour, stirring briskly.
Slowly incorporate the boiling cream or cream and milk mixture.
Transfer the mixture to a clean saucepan and stir over low heat until thick.
Remove from heat and stir well.
Return to heat and let it simmer for 6 to 8 minutes.
Finish and flavor
Pour into a basin and immediately add the pounded sugar, butter, and lemon rind or flavoring.
If desired, mix in the crushed ratifias for added flavor.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the cream as they set with heat and add richness and a smooth texture.
- Fine flour
- Stabilizes the custard by thickening it along with the yolks so it holds its body.
- Cream
- Provides the liquid base and richness that gives the custard its smooth, creamy texture.
- Pounded sugar
- Adds sweetness and helps balance the richness of the cream and yolks.
- Butter
- Adds fat that gives the finished cream a glossy, smooth mouthfeel.
The step that matters
Adding the yolks to the flour. Beaten yolks mixed into flour without stirring briskly can form lumps. Keep stirring as the liquid is added so the flour and yolks blend evenly before heating.
