Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Pudding Sauce, No. 2
Ingredients
Directions
Make the sauce base
In a pot, combine boiling water and a pinch of salt.
Add butter and stir until melted.
Mix flour with cold water, then stir into the boiling mixture.
Boil until it thickens like soft custard.
Finish and serve
Set aside and beat eggs until light.
In a bowl, cream together the beaten eggs and sugar.
Pour half of the hot mixture into the egg mixture, stirring well.
Serve immediately and reserve the rest for a second serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the boiling liquid into a soft, smooth custard-like sauce.
- Eggs
- Enrich the sauce and add body and a richer texture when beaten in.
- Butter
- Adds fat for richness and a smoother mouthfeel to the sauce.
- Sugar
- Adds sweetness and balances the savory-leaning starch and egg.
The step that matters
Pour half of the hot mixture into the egg mixture, stirring well. Adding hot liquid to eggs too quickly can scramble them. Stirring constantly while pouring gradually raises the egg temperature so the sauce stays smooth.
