Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Cream Toast
Ingredients
Directions
Make the cream sauce
Heat the milk in a saucepan until boiling.
Add the butter and stir until melted.
In a bowl, mix the flour with the cream until smooth.
Gradually add some of the boiling milk to the flour mixture, stirring to prevent lumps.
Pour the mixture back into the saucepan with the boiling milk and cook for a few moments.
Add salt to taste.
Remove from heat and stir in the beaten egg.
Serve
Strain the mixture over lightly buttered toast.

Flour and butter barely smell alike, yet cooks put them together in 124,287 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
- Milk
- Forms the liquid base of the sauce and carries the other ingredients.
- Flour
- Thickens the cream and milk into a smooth, lump-free sauce as it cooks.
- Rich cream
- Adds richness and body, giving the sauce a smoother, fuller mouthfeel.
- Egg
- Adds richness and thickening power when stirred into the hot sauce off the heat.
- Butter
- Adds fat and flavor to the sauce.
The step that matters
Stir in the beaten egg off the heat. Egg proteins set when heated, so adding the egg to a very hot sauce can scramble it. Removing the pan from the heat first lets the egg thicken the sauce gently and keeps it smooth.
