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 ↓
Sour Cream Dish
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Beat the butter and sour cream together until foamy.
Add the egg yolks and salt, mixing well.
Stir in the grated white bread.
Gently fold in the stiffly beaten egg whites.
Bake
Pour the mixture into a china baking dish.
Bake at 400°F (200°C) for 1 hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and fat, giving the bread a tender, rich crumb.
- Sour cream
- Adds moisture and tang, keeping the bread soft and moist.
- Egg yolks
- Add richness and help bind the mixture as it sets.
- Egg whites
- Whipped and folded in, they lighten the batter and help it rise.
- Grated white bread
- Absorbs liquid and gives the bake body and structure.
The step that matters
Gently fold in the stiffly beaten egg whites. Whipped egg whites trap air that gives lift. Stirring vigorously deflates them, leaving a dense bake, so fold with a light, sweeping motion until just combined.
