Why it works: Bread and butter 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 ↓
Cream Toast
Ingredients
Directions
Prepare the toast
Toast the bread until golden brown.
Melt 1 tablespoon of butter in a dish filled halfway with boiling water.
Dip each slice of toasted bread in the melted butter for a second and place in a deep heated dish.
Make the cream
Heat the milk until scalding hot but not boiling.
Thicken the milk with flour and let it simmer until cooked.
Add the remaining butter and the beaten egg whites to the milk, bringing it to a boil.
Assemble and serve
Pour the mixture over the toast, lifting the slices to allow the cream to run between them.
Cover closely and set in the oven for a few moments before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Stale bread
- Dry, sturdy slices absorb the butter and cream without falling apart.
- Milk
- Forms the base of the cream sauce that coats and soaks into the toast.
- Butter
- Adds richness and flavor, and helps coat the toast so it stays tender.
- Egg whites
- Beaten stiff and folded into the hot milk, they add lightness and body to the cream.
- Flour
- Thickens the milk as it cooks, giving the cream body so it clings to the toast.
The step that matters
Thickening the milk with flour. Flour must be cooked in the simmering milk long enough to swell and lose its raw taste. Stirring it in smoothly prevents lumps, and the starch then thickens the liquid so it coats the toast rather than running off.
