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 ↓
Onion Pudding
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
Preheat the oven to 350°F (175°C).
Make the pudding
In a bowl, combine chopped onions, sweet milk, bread, eggs, butter, pepper, and salt. Mix well until combined.
Pour the mixture into a pudding dish.
Bake
Bake in the preheated oven until set and golden, about 30-40 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the mixture and set into a firm, custard-like texture when baked.
- Bread
- Soaks up the milk and gives the pudding body and a softer crumb.
- Sweet milk
- Provides moisture and liquid that the eggs set in during baking.
- Onions
- Add savory flavor and moisture to the pudding.
- Butter
- Adds richness and fat, helping the top turn golden in the oven.
The step that matters
Bake until set and golden. Eggs set as their proteins coagulate with heat. Underbaking leaves the centre loose, while overbaking can make the custard dry and rubbery. Watch for a firm centre and a golden top.
Swap the onion
How well each one fits the dish's main ingredients (milk, bread, egg, butter, pepper):
