Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
To Make Milk Toast
Ingredients
Directions
Make the sauce
Melt the butter in a toast pan and sprinkle in the flour, mixing well with a spoon.
Gradually add the boiling water while stirring continuously until combined.
Stir in the milk or cream and heat until it just begins to boil.
Assemble and serve
Toast the bread until light brown, then dip each piece in the hot mixture one at a time.
Layer the dipped bread in a dish and spoon more of the mixture over each piece.
Once all the bread is in the dish, pour the remaining mixture over the top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the sauce with fat, giving it a rich flavour and smooth mouthfeel.
- Flour
- Thickens the sauce as it combines with the fat and hot liquid.
- Milk or cream
- Forms the liquid base of the sauce, adding creaminess and body.
- Bread
- Absorbs the hot sauce, becoming soft and moist while holding its shape.
The step that matters
Adding the boiling water gradually. Adding liquid slowly while stirring keeps the flour from clumping. Lumps form when flour meets liquid all at once, and they are hard to smooth out later.
