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
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the toast
Toast the bread until golden brown.
Melt 1 tablespoon of butter in a dish half full of 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, then bring 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 a 350°F (175°C) oven for a few moments before serving.

Butter and flour 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
- Bread
- Forms the base that soaks up the cream and holds its shape.
- Milk
- Provides the liquid that becomes the cream when thickened.
- Butter
- Adds richness and flavour, and coats the toast so it absorbs less cream.
- Egg whites
- Beaten stiff, they add lightness and help the cream set as it heats.
- Flour
- Thickens the milk so it clings to the toast instead of running off.
The step that matters
Cooking the flour into the milk. Flour must simmer long enough to cook fully and thicken the milk smoothly; undercooked flour leaves a raw, pasty taste and a thin, lumpy cream.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
