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 ↓
Milk Toast
Ingredients
Directions
Make the sauce
Heat the milk in a double boiler until nearly boiling.
Mix the flour with a little cold milk until smooth.
Stir the flour mixture into the hot milk and cook for 1 minute.
Season with salt and butter.
Assemble
Pour the mixture over slices of toast in a deep dish.
If using very dry bread, moisten it in hot water before adding the milk mixture.

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 adds dairy richness and flavor.
- Flour
- Its starch thickens the hot milk into a smooth, pourable sauce.
- Butter
- Adds fat for richness and a silky mouthfeel.
- Slices of toast
- Soak up the sauce and turn soft while keeping some structure.
The step that matters
Mixing the flour smooth before adding it to the hot milk. Flour dropped straight into hot liquid clumps as its outer starch gels before the inside hydrates. Blending it with cold milk first spreads the starch evenly, so the sauce thickens smoothly. Cooking it for the stated minute also helps cook off the raw flour taste.
