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 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 boiling milk to the flour mixture, stirring to prevent lumps.
Stir the mixture back into the boiling milk and cook for a few moments.
Season with coarse sea salt to taste.
Remove from heat and stir in the beaten egg.
Serve
Strain the mixture over lightly buttered toast.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the cream mixture into a smooth, lump-free sauce as it cooks.
- Egg
- Enriches and thickens the sauce when stirred in off the heat.
- Butter
- Adds richness and a silky mouthfeel to the sauce.
- Rich cream
- Gives the sauce body, fat and a smooth, creamy texture.
- Milk
- Forms the liquid base that the flour and cream thicken.
The step that matters
Remove from heat and stir in the beaten egg. Adding egg to a very hot mixture can scramble it. Taking the pan off the heat first lets the egg thicken the sauce gently and smoothly.
